Problems solved by technology

But still using this traditional so-called retrieval method based on image content to classify and display images, the result of mixed image types will inevitably appear, and only two types can appear at the same time, which does not help to automatically classify images according to other natural characteristics of images. into several categories

Embodiment Construction

[0021] The present invention is further described below in conjunction with accompanying drawing example song.

[0022] The image to be processed can be any image format image file, such as bmp, jpg, gif, tiff, etc. The sources of image resources can be image resources provided on the Internet, specialized image libraries, or image materials collected by individuals.

[0023] The image hierarchical classification method described in the present invention is developed into a software program and stored in a computer. The computer described here can also be replaced by a data processing device with similar digital computing capabilities such as a PDA.

[0024] When it is necessary to classify the image to be processed, the program executes the following steps in sequence, and the program flow is as follows: figure 1 shown.

[0025] 1) Read the color value of each pixel in each image to be processed (color image has three values ​​of R, G, and B) or gray value (black and white ...

Abstract

This invention relates to an image layer sorting method belonging to image processing and analyzing technology realm. It, based on large scale images on internet and phenomenon of image index with similar gray scale and image crossover with similar allocation, different sorts, provides an image layer sorting method, which can describe the image by layer abundance and evenness according to the calculation of Ftup of digit image color or brightness( gray scale) to provide a solution to sort the image index result.

Description

technical field [0001] The invention belongs to the technical field of image processing and analysis, and describes the characteristic of the image by providing a calculation method for the equalized distribution factor of the image color or brightness (gray scale), so as to classify the image by using the characteristic. Background technique [0002] The large-scale emergence of images on the Internet makes the image sorting, indexing, and retrieval technologies attract everyone's attention. However, at present, image classification and retrieval mainly use keyword matching (image name matching, such as Google's image search engine; or keywords extracted from surrounding text on image webpages) to classify; or image color distribution to retrieve and classify images . The former does not understand the content of the image, but defines and classifies it based on the webpage producer or the shooting of the picture, and the producer’s understanding of the picture; the latter...
