Embodiment Construction

[0036] refer to Figure 1 to Figure 7 , an image processing method for an electrophoretic electronic paper detection device, comprising the following steps:

[0037] Step 1. Using a photographic device (such as a camera, etc.) to take multiple shots of the electronic paper (the content displayed on the electronic paper) is used to obtain a sample image set composed of multiple photos of the electronic paper polluted by light.

[0038] Step 2. Randomly select a sample image in the sample image set, convert the sample image into a grayscale image, and draw a three-dimensional image of the sample image.

[0039] Step 3, adopt Gabor wavelet to carry out optical noise removal to sample image, obtain the sample image after filter processing, and draw the three-dimensional picture of the sample image after denoising, the output function of Gabor wavelet is:

[0040]

[0041] Among them, i is the data matrix of the sample image;

[0042] x is the row number of data matrix i;

Abstract

The invention discloses an image processing method of electrophoretic electronic paper detection equipment, which comprises the following steps of: 1, shooting electronic paper for multiple times to obtain a sample image set consisting of a plurality of electronic paper photos polluted by light; 2, randomly selecting one sample image in the sample image set, converting the sample image into a grayscale image, and drawing a three-dimensional image of the sample image; 3, carrying out optical noise removal on the sample image by adopting Gabor wavelets to obtain a filtered sample image, and drawing a three-dimensional image of the denoised sample image; 4, calculating a variance value of the filtered sample image and the original sample image by using a variance formula S, if the variance value of the filtered sample image is greater than 60% of the variance value of the original sample image, entering a step 3, otherwise, entering a step 5; 5, acquiring a filtered image, and optimizingthe filtered image; The image content of the shot electronic paper is consistent with the display content of the electronic paper, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of image restoration, in particular to an image processing method of an electrophoretic electronic paper detection device. Background technique [0002] With the development of flat-panel display technology, various display technologies are widely used in people's lives, but all kinds of flat-panel display technologies currently used in the mainstream have the same problem, that is, the display effect is not good when the external light is strong, and the display effect is not good when used. The energy consumption in the process is too large, and the electrophoretic electronic paper display has the characteristics of ultra-low energy consumption and paper-like display, and it will inevitably occupy a place in the mainstream of future display technology development. [0003] When we are shooting e-paper, since we are not in a closed dark space, the image obtained by shooting is affected by light noise, and t...
