基于Matlab空间域算法的图像增强技术的研究与应用

The research and application of the image enhancement techniques in the spatial domain based on Matlab

图像因对比度明显不足或图像细节成像模糊,以及采用ADS方法来实现灰度显示的等离子体显示器(PDP)显示图像时会出现假轮廓等现象;本文针对不同的图像处理应用领域,基于不同的图像降质原理,采用了基于空域的点运算算法和邻域去噪算法对图像进行增强处理。并通过Matlab软件对数字图像进行仿真测试。通过有目的地强调图像的整体或局部特性,增强图像中的有用信息,使图像与视觉响应特性更为匹配。经仿真测试验证,基于空域算法的图像增强技术可以有效地解决这些问题。

Image contrast is obviously insufficient or image details are blurred, and ADS method is used to realize the false contour and other phenomena of display image. This paper is based on the different image processing applications, based on different image quality reduction principle, using the algorithm based on airspace and neighborhood denoising algorithm to enhance processing. Digital images are simulated by Matlab software. By using the objective to emphasize the overall or local characteristics of the image, and enhance the useful information in the image, so that the image and the visual response characteristics more matching. The simulation results show that the image enhancement technology based on the spatial domain algorithm can effectively solve these problems.
