Embodiment Construction

[0035] Below in conjunction with embodiment and accompanying drawing, the present invention will be further described:

[0036] Such as figure 1 As shown, the present invention is based on the traversal technology, and sets the adaptive parameter traversal step size according to the change of the image content of the region of interest, traverses a single parameter or a combination of parameters, and simultaneously displays the multi-frame processing results for the user to select a satisfactory image, specifically:

[0037] Step 1: The user frames the region of interest in the original image, which is the entire region by default. The image of the region of interest is represented by I, and the pixel at position (x, y) is represented by I(x, y).

[0038] Step 2: The user selects the parameter or parameter set Θ that needs to be adjusted.

[0039] Step 3: Parameter Space Estimation

[0040] The total energy is defined as follows:

[0041]

[0042] The effective traversal...

Abstract

The invention relates to a parameter adjustment method used for digital image processing. What is often needed is to manually adjust various parameters step by step in the digital image processing process by staff through existing digital image processing software, processing quality depends on experience of users, and manual input frequency determines that image processing parameter adjustment can be only restricted to a limited range. The parameter adjustment method is based on traversal techniques, the self-adaptive parameter traversal step length is set according to image content changes of a region of interest, a single parameter or combined parameters are traversed, and multi-frame processing results are displayed simultaneously for allowing the users to select satisfying images. According to the parameter adjustment method, on the basis that modeling is not needed, the optimal parameter selections are obtained within a certain range, the users are helped to obtain images meeting specific demands of the users, and the parameter selection speed is high.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, and relates to a parameter adjustment method used in digital image processing. Background technique [0002] Existing digital image processing software often requires the user to manually adjust each parameter gradually during the digital image processing process. The quality of processing depends on the experience of the user, and the frequency of manual input determines the range of image processing parameter adjustments. It can be limited to a very limited range, which is not conducive to the improvement of image processing quality in the image processing process. This problem is even more serious when the uncorrelation between multiple parameters is not satisfied. [0003] In some specific applications, it is possible to model the problem, define a certain criterion function, and use optimization calculations to obtain the optimal parameters under the criterion to improve th...
