Embodiment 1

[0027] This embodiment provides a computer image recognition method, and implements the present invention through the basic necessary technical features to solve the problems raised in the technical background section of this application document.

[0028] Specifically, such as figure 1 As shown, the embodiment of the present invention provides a computer image recognition method, specifically as follows:

[0029] The color value of each pixel in the image to be recognized is extracted to generate a color matrix, and the coordinates of each pixel are established according to the color matrix. In the present invention, each pixel point in the image has its uniquely corresponding coordinates, and each pixel point also has its uniquely corresponding color value, so in the coordinate matrix corresponding to each pixel point of the image, each The coordinates of the pixel point will correspond to a color value one by one.

[0030] Compare the color value of each pixel point with ...

Embodiment 2

[0035] This example is based on Example 1 and optimizes the implementation in Example 1, so that this example is more stable and has better performance during operation, but it is not limited to the one described in this example implementation.

[0036] Specifically, such as Figure 1-2 As shown, in this embodiment, when comparing the color value of a pixel with the color values ​​of its surrounding adjacent pixels, when the color value of this pixel and the color values ​​of all surrounding adjacent pixels When the difference is within the set color difference range, the difference between the color value of the pixel and the color values ​​of all adjacent pixels around it is obtained, and the average of all the differences is calculated, and The average is added to the color value of the pixel and replaces the original color value of the pixel.

[0037] In this embodiment, when the item is identified, the color of the image can be smoothed at the same time, and the average...

Abstract

The invention discloses a computer image recognition method, which comprises the steps of extracting color values of pixel points in a to-be-recognized image, generating a color matrix, and establishing coordinates of the pixel points according to the color matrix; respectively comparing the color value of each pixel point with the color values of the adjacent pixel points around the pixel point;when the difference value between the color value of the pixel point and the color value of at least one adjacent pixel point around the pixel point is not in a set color difference range, extractingthe coordinate of the pixel point in the color matrix, and repeating the process until all pixel points are traversed; obtaining one or more functions according to all the extracted coordinates; and searching in an image library according to the obtained function to obtain the name of the article, and outputting the name. According to the method, the pixel points of the image to be identified areextracted, the outline of the object is separated from the pixel points, the object is identified according to the outline of the object, and finally the object in the image is output and obtained.

Description

technical field [0001] The invention relates to the field of computers, in particular to a computer image recognition method. Background technique [0002] Image recognition is a basic technical means of artificial intelligence. At present, image recognition is by extracting the features of each pixel in the image to be recognized, and comparing it with the features of each pixel in the existing image. When the similarity of point features is within the set range, the item in the existing image is output as the item in the image to be recognized. Such a recognition method needs to extract the pixels of each compared image and perform a large amount of comparison work, so that when the computer performs calculations, it will greatly increase the amount of calculated data, so that the computer can recognize the image. Very slowly. Contents of the invention [0003] The purpose of the present invention is to overcome the problems existing in the above-mentioned prior art, a...
