Figure 4 (a, c) show the original image and the differential evolution algorithm for enhanced results can be seen from the enhanced contrast markedly improved, clearer image details, edge feature more prominent. b, c shows the waveletbased hybrid geic algorithmbased Comparison of Image Enhancement: waveletbased enhancement method to enhance image detail out some of the image visual effect is an improvement over the original image, but the enhancement is not obvious。 and Hybrid geic algorithm based on adaptive transform image enhancement effect is very good, image details, texture, clarity is enhanced pared with the results based on wavelet transform has greatly improved the image of the postanalytical processing helpful. Experimental enhancement experiment using wavelet transform sym4 wavelet, enhanced differential evolution algorithm experiment, the parameters and the values were ,. For a 256 256 size image transform based on adaptive hybrid geic algorithm in Matlab image enhancement software, the puting time is about 2 seconds, operation is very fast. From TABLE I, objective evaluation criteria can be seen, both the edge of the protection index, or to enhance the contrast index, based on adaptive hybrid geic algorithm pared to traditional methods based on wavelet transform has a larger increase, which is from This section describes the objective advantages of the method. From above analysis, we can see 安徽工業(yè)大學 畢業(yè)設計（外文翻譯）說明書 ……………………………………………………裝………………訂………………線…………………………………………………………………… 第 7 頁 共 23 頁 that this method. From above analysis, we can see that this method can be useful and effective. VI. CONCLUSION In this paper, to maintain the integrity of the perspective image information, the use of Hybrid geic algorithm for image enhancement, can be seen from the experimental results, based on the Hybrid geic algorithm for image enhancement method has obvious effect. Compared with other evolutionary algorithms, hybrid geic algorithm outstanding performance of the algorithm, it is simple, robust and rapid convergence is almost optimal solution can be found in each run, while the hybrid geic algorithm is only a few parameters need to be set and the same set of parameters can be used in many different problems. Using the Hybrid geic algorithm quick search capability for a given test image adaptive mutation, search, to finalize the transformation function from the best parameter values. And the exhaustive method pared to a significant reduction in the time to ask and solve the puting plexity. Therefore, the proposed image enhancement method has some practical value.
