[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings:

[0031] Figure 1 For a flow chart of the printing and dyeing method based on artificial intelligence technology of the present invention, please refer to Figure 1 The printing and dyeing method based on artificial intelligence technology of the present invention comprises the following steps:

[0032] S101: Receive and store a first image. Optionally, step S101 further includes: a customized image receiving step, for receiving a customized personalized first image through a client. The first image can be a photo or picture taken by a user client to meet the user's personalized customization requirements.

[0033] S102: Automatically process the first image to make it meet preset printing and dyeing parameter requirements, and obtain a second image.

[0034] Optionally, the step S102 further includes directly processing the first image using an image processing algorithm, and automatically editing the colors and lines of the first image to obtain the second image while retaining the subject features of the first image.

[0035] Optionally, the step S102 may also perform stylization processing on the first image to obtain the second image that meets the preset printing and dyeing parameter requirements, wherein the stylization processing includes but is not limited to cartoonization and oil painting.

[0036] Optionally, the step S102 may first perform stylization processing on the first image, and then use an image processing algorithm to directly process the first image, and automatically edit the color and lines of the first image while retaining the subject characteristics of the first image to obtain the second image that meets the pre-set printing and dyeing parameter requirements; wherein the stylization processing includes but is not limited to cartoonization and oil painting.

[0037] In some of the embodiments, the stylization processing can directly call the existing commercial artificial intelligence open platform API interface; wherein the existing commercial artificial intelligence open platform API interface includes the Baidu artificial intelligence open platform API interface;

[0038] Actively change the image to make it suitable for printing before printing and dyeing. The core method is to write code based on algorithms such as bilateral filtering and median filtering to remove image noise and ensure the clarity of graphic edges. The example processes image information by referencing the OpenCV graphics processing library to reduce the noise of the image, and sets parameters such as the number of sampling and filtering according to printing and dyeing requirements to ensure the printing and dyeing quality after image processing; it can also be used to change the internal color gradient, make it closer to the same color, reduce color gradient, and strengthen contour lines, so that the quality effect after printing and dyeing is better.

[0039] In the embodiment of the present invention, artificial intelligence related technology software written in programming code can be used to analyze and change the image, and the image color, pixel position, and line can be fully changed while retaining the image characteristics, as follows:

[0040] Call the OpenCV graphics processing library, use the bilateral filtering method and the median filtering method to reduce the noise of the image; OpenCV provides a function to convolve the kernel with the image, and blur the image by convolving the image with the low-pass filter kernel, which is helpful to eliminate image noise. OpenCV mainly provides four types of blurring technology. The embodiment of the present invention uses median filtering and bilateral filtering. Median filtering is mainly used to ensure the important problem of image quality during printing and dyeing, such as salt and pepper noise; bilateral filtering is mainly used to remove noise while keeping the edges clear and sharp. The above method is implemented by using artificial intelligence related technology software made of programming code to analyze and change the image. While retaining the characteristics of the image, it can achieve a comprehensive change in image color, pixel position, and lines. Artificial intelligence programs can be written in a variety of computer languages, such as C++, JAVA, and PYTHON.

[0041] Median filtering replaces the value of a point in the image data with the median of the values ​​of all points in the area of ​​that point, thereby effectively removing large-area noise points that have a significant impact on the printing and dyeing effect.

[0042] Bilateral filtering uses a weighted average method while considering the Euclidean distance. For example, ordinary Gaussian low-pass filtering only considers the influence of position on the central pixel and the radiation difference in the pixel range domain, such as the similarity between the pixel in the convolution kernel and the central pixel, color intensity, depth distance, etc., and uses the weighted average of the brightness values ​​of the surrounding pixels to represent the intensity of a certain pixel. In the edge area of ​​the image, the pixel range domain weight becomes larger to strengthen and maintain the contour information of the image.

[0043] The embodiment of the present invention uses Python to write a program, and the calling functions are cv2.medianBlur() and cv2.bilateralFilter(), and the filtering parameters are set at the same time to ensure the image printing and dyeing quality.

[0044] For image stylization, you can call Baidu's AI commercial API interface or directly use an AI program based on the neural network image style transfer program to stylize the image; you can also use the AI ​​algorithm to improve detail sharpness, and quickly and efficiently improve the resolution and enhance the detail when the resolution is lower than the requirement. Finally, images that meet the printing and dyeing requirements can be generated in a short time and with greatly reduced labor costs, and quickly transmitted to the relevant systems of the printing and dyeing company, realizing a fast, efficient, low-cost and flexible processing process.

[0045] To meet the needs of artistic aesthetics, when images need to be stylized, the Baidu AI Open Platform API interface is called to stylize the images. The main reason for using the Baidu interface is that the interface provided by Baidu has begun commercial applications, with fast speed, high stability, and no need to build a server. The Baidu Image Stylization API interface has the following features: using adversarial generative network technology and neural network image style transfer technology, combined with face detection, hair segmentation, portrait segmentation and other technologies, it can tailor a thousand different two-dimensional anime images for users, and support the generation of two-dimensional anime portraits through parameter settings.

[0046] In all embodiments of this process, stylization processing can also be directly implemented on the first image through an image style transfer program of an artificial intelligence neural network. For example, using a Python third-party library, Google's "Style Transfer" open source program of the 'TensorFlow' artificial intelligence toolkit. This program uses deep learning to transfer styles between images. The same functions and results as when calling the above API interface can be achieved.

[0047] The artificial intelligence technology is used to make the stylized image suitable for printing and dyeing. The bilateral smoothing filter is used again to set relevant parameters to ensure that the image is suitable for printing and dyeing. If the stylized image meets the printing and dyeing requirements, it is directly printed and dyed.

[0048] S103: Outputting the second image to a printing terminal, and printing the second image on a physical medium through the printing terminal.

[0049] Optionally, the step S103 also includes transmitting the second image to a printing and dyeing terminal; wherein the step of transmitting to the printing and dyeing terminal includes at least one method of retaining information through email, APP and web page.

[0050] Optionally, the step S103 includes first printing the second image on a printing and dyeing adhesive paper, and then heating and pressing the second image on the physical medium through a printing and dyeing device.

[0051] Optionally, the step S103 includes using an inkjet printing device to directly print the first image on the physical medium.

[0052] When the embodiment of the present invention adopts the email method for sending, an executable program of the mail sender that can transmit picture information and input address information is executed in the WINDOS system to realize mail transmission. The program is written in python and calls the smtplib, MIMEText and Header libraries, which can realize automatic batch sending of mails. The system automatically matches the order pictures and the corresponding printing and dyeing media, and sends the address bar information entered by the customer at the same time, realizing a one-click flexible manufacturing process from shooting creation to printing and dyeing manufacturing.

[0053] When the embodiment of the present invention is executed in the app mode, QPython 3L is used to directly convert the pictures taken by the mobile phone into new pictures corresponding to the requirements, and a dedicated APP for printers such as HP or Epson is installed to print the thermal transfer stickers of the required pictures on sublimation transfer paper, and then perform thermal transfer printing and dyeing. The process from the mobile terminal that can take pictures with the mobile phone to the flexible printing and dyeing manufacturing is realized.

[0054] To prevent the images from sticking to each other on the physical medium, lay the printed and dyed physical medium flat or stack it on a flat plate to dry in the shade.

[0055] Figure 2 FIG. 1 is a flow chart of an embodiment of a printing and dyeing method based on artificial intelligence technology of the present invention, as shown in FIG. Figure 2 As shown, the printing and dyeing method provided in the present application includes the following steps:

[0056] S200, the system receives and reads the original image data, establishes a data set, and records the data set in a cache medium;

[0057] S201, transfer the data set to the algorithm program, call the OpenCV image processing library, use bilateral filtering and median filtering to remove image noise. Set the parameter sampling number to 2 and the bilateral filtering number to 7;

[0058] S203, determining whether image stylization processing is required;

[0059] If image stylization is required, use an artificial intelligence image processing program to process the image, use the Baidu artificial intelligence commercial API interface, and the interface call method is POST; or use a neural network-based image style transfer program and perform data set training to transform new images. The new image retains the characteristics of the original image based on the pre-set parameters, and automatically changes the original image pixels, intensity, and color, etc., to make it more suitable for printing and dyeing or change it to the required image style that meets the printing and dyeing conditions.

[0060] If the printing and dyeing requirements are still not met after stylization processing, bilateral filtering and median filtering are performed again; if the requirements are met, the image is transmitted to a server via email or APP.

[0061] S204, receiving a new image from the server and sending the new image data information to the printing device.

[0062] S205, the printing and dyeing equipment receives the new image, places the printed medium, determines the printing and dyeing position, and performs the printing and dyeing operation.

[0063] S206, finally performing drying and cooling operations.
