specific Embodiment

[0127] In the specific embodiment of the patent of the present invention, on the intelligent terminal, fast processing is performed on the handwritten digital color image, so as to quickly and accurately extract the handwritten digital in the processed image, and further use it in relevant scientific research and application. Specific examples are as follows:

[0128] In daily life, the captured image may be blurred due to pixels or shooting techniques, including Gaussian noise, dark background, etc.; the original color image selected in this example conforms to the above characteristics, and the foreground is a blue handwritten number 8 , the background is dark gray, including Gaussian noise and isolated points, the size of the color image is 1080x1080 pixels, and the size of the color image is 918KB; for example image 3 As shown, the original color image is directly processed, that is, when the image compression is turned off, all the processed images have the same size as ...

Abstract

The invention discloses a color image quick processing method based on an intelligent terminal. The invention belongs to the technical field of color image processing. The method comprises the specific steps that interface design is conducted on an application program of the intelligent terminal; selecting and opening a color image through interface design; observing whether the selected color image needs to be compressed or not; graying processing is carried out on the color image after compression processing, so that graying of the color image is enhanced; gaussian filtering processing, binarization processing, expansion processing and corrosion processing are successively carried out on the grayed images; performing interface display on the processed image and the processing time consumption; and finally, storing the processed image. The method can be quickly used for processing and analyzing the image, the original image processing time is 13.7 seconds, particularly, only 1.5 seconds are needed after image compression is used, and the processing efficiency is improved by nearly 10 times; therefore, the extraction efficiency of the target object is improved, and the required processing time is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of color image processing, in particular to a method for quickly processing color images based on an intelligent terminal. Background technique [0002] Digital image processing technology is an in-depth application of computer technology. Through digital image processing technology, images can be processed in color image gray scale, noise filtering, image enhancement, image restoration, feature segmentation, feature extraction and other operations. Specifically, it includes the process of converting image signals into digital signals through conversion technology, and then performing related processing through computer processing technology. [0003] At present, digital image processing technology usually includes many devices, mainly digital image collectors, image processing computers or servers, cameras, image display terminals and other equipment. By effectively combining these devices, a complete digi...
