Embodiment Construction
[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0028] The example of the present invention provides a kind of image color space conversion, the method for feature recognition and feature extraction, such as figure 1 shown, including the following steps:
[0029] Step 1: Define a new color space, map the original tongue map to the new color space according to the transformation matrix, and obtain the tongue map after the enlarged prick feature, as shown in image 3 . figure 2 It is a three-dimensional information map of tongue map color in RGB space.
[0030] Step 2: Combined with the maximum inter-class variance algorithm, define the size of the filter operator according to the size of the tongue map, and dynamically define the weighting coefficient of the operator according to the color information of the tongue map points;
[0031] Step 3: Use the operator generated in step 2 to perf...
