针对传统图像增强算法存在的不足，提出一种基于 Android 平台的图像增强算法。首先采用同态滤波对图像进行预处理，并用小波变换分解图像；然后对图像进行对比度拉伸和亮度增强，消除图像中的噪声等；再采用小波变换重构图像各分量，得到增强后的图像；最后在 Android 平台上实现图像增强算法，并用仿真实验测试其性能。仿真结果表明，该算法解决了传统图像增强算法的不足，得到了较理想的主观视觉效果，加快了图像增强的速度，可满足图像增强的实时性要求。
針對傳統圖像增彊算法存在的不足，提齣一種基于 Android 平檯的圖像增彊算法。首先採用同態濾波對圖像進行預處理，併用小波變換分解圖像；然後對圖像進行對比度拉伸和亮度增彊，消除圖像中的譟聲等；再採用小波變換重構圖像各分量，得到增彊後的圖像；最後在 Android 平檯上實現圖像增彊算法，併用倣真實驗測試其性能。倣真結果錶明，該算法解決瞭傳統圖像增彊算法的不足，得到瞭較理想的主觀視覺效果，加快瞭圖像增彊的速度，可滿足圖像增彊的實時性要求。

In order to obtain more ideal effect of the image enhancement,the authors presented an image enhancement algorithm based on Android platform.Firstly,homomorphism filtering was used to preprocess the image,and wavelet transform was used to decompose the image,and then the contrast stretching and brightness enhancement were used to eliminate the unfavorable influence on the image,and wavelet transform was used to reconstruct the components after image enhancement, finally,the image enhancement algorithm was implemented at the Android platform and the performance was tested by simulation experiment.The simulation results show that the proposed algorithm has the advantages of Android and can obtain more ideal visual effect,speeds up the image enhanced speed,so it can meet the image enhancement real-time requirements.
