Comprising characteristics of image corresponding with the passage, original image taking under the corresponding component of the passage can be obtained in single channel image
Value scope and distribution situation.Three single channel images are overlapped original image is obtained.
It will be appreciated that any one color all has corresponding and unique distribution characteristicss in color space,
A corresponding span on each component in color space.Therefore, after the color for wanting to extract is determined, can be in face
A span is determined on each component in the colour space so that the original image within the span is extracted for only including
The parts of images of color.Specifically, after above-mentioned original image to be decomposed into tri- single channel images of X, Y, Z, can basis
The intrinsic value distribution characteristicss in color XYZ color space are extracted, and determine the value model for color being extracted in each component channel
Enclose, the span should be less than intrinsic span of the extraction color in the color space.
In a kind of mode of possible enforcement, also original image can be transformed into HSI color spaces, be partitioned in original image
During yl moiety image, each component of yellow in HSI can determine that according to intrinsic value distribution of the yellow in HSI color spaces

Region and the mask image of the second gray areas, can specifically include：
The pixel that value in original image in each single channel component meets span is converted to white, by original image
Rest of pixels be converted to black, generating only includes the mask image of black region and white portion.
In the specific implementation, all pixels of original image can be traveled through according to the span that determines, will can be fallen in value
Enter the original image pixel in above-mentioned span and be converted into the white image that gray scale is 255, and value is not fallen within span
Interior original image pixel is converted into the black image that gray scale is 0.Thus, can be directed to color generation one is extracted only comprising two ashes
The image of degree, wherein, is white comprising the image for extracting color part, is black not comprising other images for extracting color.With
Color is extracted for, as a example by yellow, after judging through above-mentioned value, original image is that image as shown in Figure 2 b can be generated such as
Shown in Fig. 2 c with extract color yellow corresponding to mask image.Can be seen that by the contrast images of Fig. 2 b and Fig. 2 c
White portion in the mask image of generation has yellow for only including the part of yellow, that is, the mask image for generating in original image
The profile of image and not have yellow image image information.Can after the mask image of generation and original image are done image operation
Only included the parts of images for extracting color.
