Problems solved by technology

[0006] However, the above-mentioned identification method applied to the color of the vehicle body uses an algorithm based on dynamic images. Compared with the algorithm based on static images, the calculation amount required by the dynamic algorithm is relatively large, and the accuracy of the obtained identification results is relatively poor; in addition, The above color recognition method is to recognize the color of all pixels in the entire vehicle video image after the background is removed, which not only has a large amount of calculatio

Embodiment Construction

[0029] In one embodiment of the present invention, the color of the pixels in the feature area is identified by a support vector machine classifier used for pixel color recognition in the feature area, and based on the pixel color recognition results, the statistics of the pixel points of various colors in the feature area are calculated. According to the feature vector, the color of the feature area representing the color of the object to be identified is identified by the support vector machine classifier for area color identification. The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] figure 1 A schematic flowchart of a color recognition method according to an embodiment of the present invention is shown, which is used for color recognition of an object to be recognized in an image. It should be noted that, in this embodiment, the color recognition method in the embodimen...

Abstract

The invention discloses a color identifying method which includes the following steps: characteristic zones of an object to be identified in an image are defined; colors of pixel points in the characteristic zones are identified; the colors of the pixel points are calculated to acquire characteristic vectors of zone color identification and then colors of characteristic zones used for representing the color of the object to be identified are identified. The adoption of the invention can reduce calculated amount and accelerate calculation speed and enhance identification accuracy.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method for identifying the color of an object to be identified in an image. Background technique [0002] In some cases, we need to process a specific target in the captured image to obtain various features including the category of the specific target, its position, shape, size, and even color in the image, etc. Furthermore, various acquired features are used in different usage environments. [0003] Taking the vehicle monitoring that is widely implemented now as an example, in places such as public security checkpoints and expressway toll stations, vehicles on traffic roads can be monitored through the erected intelligent traffic monitoring system, for example, real-time capture by cameras to obtain high-definition Vehicle static images, using relevant recognition technology to obtain accurate vehicle-related information (such as license plate number, model ...
