Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, in order to achieve the aforementioned object of the invention, Embodiment 1 of the present invention proposes an image color extraction processing structure, and the device is realized through the following technical solutions.

[0017] The structure connection method is as follows:

[0018] The device includes: a foreground image extraction module, used to establish a background model when receiving a video image, and extract the foreground image of the video image; the first step is to normalize the image and process the module, and the processing module processes the obtained The foreground image is subjected to a color normalization process, and the normalized image is obtained as an object of image data segmentation.

[0019] In the second step, the image segmentation module is used to measure the dissimilarity of the...

Abstract

The invention discloses an image color extraction processing structure, which is used in the technical field of image processing, and solves the problems that the traditional color image segmentation device has difficulty acquiring high-quality and elaborative segmentation results and the real-time performance cannot meet the requirements of a large-scale database. The image color extraction processing structure comprises the steps of: establishing a background model when receiving a video image, and extracting a foreground image of the video image; subjecting the acquired foreground image to color normalization processing, and regarding a normalized image as an object of image data segmentation; and clustering pixels of the image by adopting an image segmentation algorithm according to dissimilarity measure of color features among the pixel points, segmenting the image into pieces of blob sub-regions, and extracting color and position features corresponding to each sub-region. The image color extraction processing structure can perform target image recognition precisely and effectively, and has high real-time performance. If not specified, the images referred in the invention are color images.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a color image color extraction processing structure. Background technique [0002] With the rapid development of multimedia technology, video data is becoming larger and larger. How to analyze, search and identify these massive video data has become an important challenge in related research fields, especially in the fields of intelligent monitoring and digital security. Hotspots and Difficulties. In order to identify and track the target object in the image, it is usually necessary to extract the image features of the target for comparison. As a highly robust visual feature, color features are more dependent on factors such as the size, direction, and viewing angle of the object itself. Small and therefore widely used. [0003] There are many ways to extract color features, such as image segmentation, which divides the image into several different color regions, and t...
