| 摘 要： | 图像增强就是通过一定的方法对图像进行处理和变换,它能有效地改善图像整体质量和局部特征,是数字图像的预处理。基于直方图均衡化和规定化处理的图像增强技术,能有效地改善图像的对比度和灰度动态范围。实验结果表明,直方图均衡化和规定化处理确能有效地改善图像的对比度和灰度动态范围,从而改善图像的可视质量。

| Abstract: | Image enhancement which is also called image pre-processing,can improve the visual quality of the whole and partial image,by transforming the image's data according to some special methods.The image enchancement based on histogram equalization and specification can improve the contrast details and the dynamic range of gray level of the image.The MATLAB experiments demonstrate that the image enchancement based on histogram equalization and specification actually make the image better in vision. |
