Abstract

The invention discloses a color classification identification method and system based on chromatogram similarity measurement, and the method comprises the steps: obtaining a to-be-identified target color image, and converting the target color image into a human visual color space image; performing multi-dimensional chromatographic conversion on each effective pixel point of the human visual color space image, and fusing chromatographic conversion results of each dimension to obtain a target chromatogram; and performing chromatographic similarity measurement on the target chromatogram and a pre-stored target category, and if a similarity measurement result is greater than a threshold value, determining that the target color image is the target category. The technical problems that in the prior art, color recognition accuracy is poor, and visual habits are not met are solved, and color recognition accuracy and interaction friendliness are improved.

Description

technical field [0001] The invention relates to the technical field of color recognition, in particular to a color classification recognition method and system based on chromatogram similarity measurement. Background technique [0002] In some practical application scenarios, it is necessary to classify or identify objects according to their colors. For example, color comparison analysis can be performed on the images of standard samples of known categories and the target to be identified, and the target can be classified or identified according to the similarity of their colors. The output image of the camera is usually a grayscale image or a color image in RGB color space. However, the grayscale image has too little information, resulting in low recognition accuracy; and the RGB color space does not conform to human visual habits, and is not suitable for color recognition. Contents of the invention [0003] For this reason, the present invention provides a color classi...
