Embodiment 1

[0059] refer to figure 1 , shows a flow chart of the steps of a method for determining the quality level of handwriting according to Embodiment 1 of the present invention. The method includes the following steps:

[0060] Step 101: Obtain the image of the target word.

[0061] In one implementation, the user can write the target word on paper, and then use the shooting device to shoot the target word to obtain the image of the target word, and then transmit the image of the target word from the shooting device to the processing terminal, or the user writes the target word on the paper After the target word is written, the target word can be directly photographed by a processing terminal with a photographing function, so as to obtain an image of the target word.

[0062] In another implementation, the user can directly write the target word on the electronic screen of the processing terminal with an electronic pen, so that the processing terminal can generate an image of the ...

Embodiment 2

[0073] refer to figure 2 , shows a flow chart of the steps of a method for determining the quality level of handwriting according to Embodiment 2 of the present invention. The method includes the following steps:

[0074] Step 201: Obtain the image of the target word.

[0075] This step is similar to the implementation process of step 101 above, and will not be described in detail here.

[0076] Step 202: Perform preprocessing on the image of the target word to obtain a first image and a second image.

[0077] In the embodiment of the present invention, this step can be implemented in the following manner, including: obtaining the target binarized image corresponding to the target word image; from the target binarized image, determining the target quadrilateral region containing the target word; Performing perspective transformation on the area to obtain the target correction area; performing corrosion processing on the target correction area to obtain the first image cont...

Embodiment 3

[0120] Figure 5 A schematic structural diagram of a device for determining the quality level of handwriting according to Embodiment 3 of the present invention is shown. refer to Figure 5 , the device 500 may include:

[0121] The first obtaining module 501 is used to obtain the target word image;

[0122] The first preprocessing module 502 is configured to preprocess the target word image to obtain a first image and a second image;

[0123] The first extraction module 503 is configured to perform writing feature extraction on the first image and the second image, and obtain a first feature vector;

[0124] The first determination module 504 is used to determine the difference parameter between the first feature vector and the second feature vector corresponding to the standard word image;

[0125] The second determination module 505 is configured to determine the quality level of writing corresponding to the difference parameter.

[0126] optional, see Figure 5 , the ...

Abstract

The invention provides a method and a device for determining the quality level of a writing style, which relates to the technical field of image processing. The method comprises the following steps: obtaining an image of a target word; Preprocessing the target word image to obtain a first image and a second image; Performing writing feature extraction on the first image and the second image, and obtaining a first feature vector; Determining a difference parameter between the first feature vector and the second feature vector corresponding to the standard word image; Determining a writing quality level corresponding to the difference parameter. According to the invention, the processing terminal can extract the writing features of the target word image, and comparing the writing features ofthe target character image with those of the standard character image, Therefore, the writing level of the target character image relative to the standard character image can be determined, so that the processing terminal can evaluate the handwriting of the calligraphy practitioner, thereby providing professional guidance for the calligraphy practitioner and improving the efficiency of the calligraphy practice.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for determining the quality level of handwriting. Background technique [0002] Calligraphy is a cultural treasure of the Chinese nation. Calligraphy education has a subtle effect on inheriting and developing the excellent traditional Chinese culture and cultivating a younger generation with higher cultural literacy. Many people need a lot of calligraphy practice out of hobbies or professional needs to achieve the desired effect. In real life, the most common way of calligraphy practice is to copy copybooks, such as copying exercises on paper or electronic writing screens . [0003] However, in practical applications, many calligraphy practitioners practice in the absence of professional instructors after calligraphy classes. Therefore, it is usually difficult for practitioners to professionally judge whether they are writing standards, which will le...
