Embodiment Construction
[0032] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0033] The flow chart of the inventive method is as figure 1 As shown, the specific steps are as follows:
[0034] (1) Detect the gray spectrum distribution of the source image, determine that it has a descending gray spectrum distribution, and then calculate the continuous bandwidth BW of the gray spectrum of the source image; as image 3 As shown in (a), it can be clearly seen that the gray spectrum of this embodiment is a descending spectrum distribution; the continuous bandwidth of the gray spectrum is BW=19.
[0035] 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 general grayscale histograms and logarit...
