| 摘 要： | 针对部分灰度图像分辨率和对比度低、噪声大、视觉特性差等特点,提出了一种基于小波变换和直方图均衡的新的图像增强方法。该方法将小波变换的多尺度、多分辨率的特点和直方图均衡化的方法相结合,同时再辅以中值滤波去噪和同态滤波增强,从而在很大程度上克服了单一的直方图均衡化进行图像增强时会丢失图像细节信息、增强图像噪声等的不足。实验结果验证文中方法对图像的分辨率和对比度增强有很好的效果。

| Abstract: | According to the characteristics of some gray images such as low resolution and contrast, high noise and poor visual characteristics, a new image enhancement method based on wavelet transform and histogram equal？ization is proposed. The characteristics of wavelet transform such as multi-scale and multi-resolution are incorporat？ed with histogram equalization method in the method, and assisted with median filter de-noising and homomor？phism filtering enhancement. So the shortcomings such as image detail loss with single histogram equalization im？age enhancement method and enhancement image noise are overcome. Experimental results show that the method has better effect for image resolution and contrast enhancement. |
