Problems solved by technology

The advantage of this method is that it is oriented to the human visual system, and the evaluation is real and comprehensive, but the evaluation results are greatly affected by uncontrollable factors such as the evaluator's personal preference and self-quality. To accurately measure, so the dispersion is large

Abstract

The invention relates to an image denoising method for selecting wavelet basis on the basis of an analytic hierarchy process. The image denoising method comprises the following steps: S1) selecting an index used for evaluating an image denoising result, establishing a relative importance judgment matrix by adopting the analytic hierarchy process, carrying out quantitative analysis on the weight of each index, and checking reliability through consistency; and S2) on the basis of index weight analysis, selecting a wavelet basis, and carrying out image denoising by adopting the analytic hierarchy process. Compared with the prior art, the invention establishes a basis frame of wavelet basis evaluation on the basis of the analytic hierarchy process, an optimal wavelet basis can be conveniently and intuitively selected, and a scientific and objective basis is provided for practical image operation.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to an image denoising method for selecting wavelet bases based on analytic hierarchy process. Background technique [0002] Analytic Hierarchy Process (Analytic Hierarchy Process, AHP) is a multi-objective decision analysis method combining qualitative and quantitative analysis proposed by American operations researcher Saaty in the 1970s. Its main idea is: first, according to the nature of the problem and the overall goal required to be achieved, the problem is decomposed into different factors according to the level, and the weight (ie, importance) of each different factor in the same level L can be determined by comparing them between each other. Paired judgments are obtained. The importance of the factors in the next level L+1 should consider not only the current level, but also the weight factor of the previous level. Therefore, it is generally necessary to calculate t...
