Embodiment Construction
[0028] The present invention will be further described below in conjunction with drawings and embodiments.
[0029] Such as image 3 Shown, the present invention comprises the following steps:
[0030] 1) Select an appropriate color space or establish a color model: For this study, choose the RGB color space. In the RGB space, it is necessary to consider selecting appropriate color features to separate chromaticity and brightness, which is helpful for detecting shadow and highlight areas. . In this space, comparing the difference between two colors is to compare the Euclidean distance of two vectors in the space, such as figure 1 shown. In the figure, D i is a difference vector, which can be decomposed into brightness E according to human visual characteristics i -α i E. i and Chroma CD i Components, from which a color model is established.
[0031] 2) When a certain color space is determined, it is necessary to select an appropriate color feature or establish a color...
