Embodiment Construction
[0037] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0038] Realize the flow chart of the inventive method as figure 1 As shown, the specific steps are as follows:
[0039] (1) Detect the gray spectrum distribution of the source image, determine the convex gray spectrum distribution, then determine the left boundary value GLeft, the right boundary value Gright and the peak value PG of the source image gray spectrum, and calculate the gray spectrum of the image Continuous bandwidth BW; such as figure 2 It can be clearly seen that the gray spectrum of this embodiment has a convex spectral distribution.
[0040] The detection method for image gray spectrum used in the step (1) of the present invention (this method is recorded in the invention patent with the patent number ZL200610054324.9) has a powerful underlying image information mining function, and has a pixel visualization The accuracy is unmatched by ge...
