灰度拉伸(Histogram Stretching):灰度拉伸是一种简单而常用的图像增强方法,通过将图像的像素值进行线性拉伸,扩展图像的对比度范围,使图像中的细节更加明显。 直方图均衡化(Histogram Equalization):直方图均衡化通过重新分布图像的像素值,使得各个灰度级在图像中的分布更加均匀,从而提高图像的对比度和细节。 滤波(Filtering)...
For improving the dynamic range of the image, a histogram equalization should be implemented and applied to the different images. The implementation of the algorithm is getting more complex. Thus, to compare the calculated results some plots with the correct results are included in the laboratory ...

To validate the effectiveness of the DWARP algorithm, it is compared with other image enhancement, image restoration, and deep learning-based methods, such as Retinex, Histogram Equalization (HE), C2Pnet3, DCP9, DCM2, PSD31, STH8, and RIDCP37. The above dehazing models are tested using ...
Histogram equalization36,37,38 enhances image contrast by redistributing pixel values to achieve a histogram closer to uniform distribution, thereby improving visual effect. However, global histogram equalization can sometimes reduce image details while ignoring local contrast enhancement. Median filtering39 ...
