Embodiment Construction
[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0053] The existing color recognition technology is difficult to effectively recognize the colors in images with complex color matching, such as stripes, grids, floral patterns, etc., and the recognition accuracy is relatively low. In order to overcome the above technical problems, this application provides a method based on The adaptive block strategy determines the main color image block of the segmented area image, and determines the color recognition scheme...

The invention discloses a color recognition method, device and equipment and a storage medium, and the method comprises the steps: segmenting an original image through an image segmentation model, andobtaining an image of each segmentation region; partitioning the segmented region image based on a preset rule to obtain sub-image blocks, and determining main color categories of the sub-image blocks according to color values of pixel points at preset positions in the sub-image blocks; classifying the sub-image blocks according to the main color types of the sub-image blocks, and respectively screening out a plurality of sub-image blocks from each type of sub-image blocks to obtain first image blocks corresponding to each type of sub-image blocks; a second image block for reflecting a main color category of the first image block being determined based on the first image block, and a color category sequence of the segmented region image being determined according to the second image block. According to the invention, the color category sequence containing the main color category of the segmented region image is determined based on the adaptive partitioning strategy, so that the accuracy and integrity of color recognition are improved.
Description
technical field [0001] The invention relates to the technical field of computer vision, in particular to a color recognition method, device, equipment and storage medium. Background technique [0002] At present, computer vision is widely used in various fields such as face recognition, security, and unmanned driving. Among them, image recognition technology is an important branch of computer vision technology, and color attributes are one of the most significant distinguishing points in images. Therefore, color recognition is particularly important in image recognition, but in practical applications, color recognition is often interfered by many factors, resulting in low recognition accuracy. For example, in the application scenario of human body structural feature extraction, the recognition of the color of each part of the pedestrian's body is not only interfered by the light factor, but also compared to the object with a larger size, more regular boundaries and a relativ...
