Web12 apr. 2024 · Image dehazing has always been one of the main areas of research in image processing. The traditional dark channel prior algorithm (DCP) has some shortcomings, such as incomplete fog removal and excessively dark images. In order to obtain haze-free images with high quality, a hybrid dark channel prior (HDCP) algorithm is proposed in … WebNatural image matting algorithms [17, 18] can be mainly divided into three categories: sampling-based matting algorithms [19], alpha propagation-based matting algorithms and deep learning-based matting algorithms. The sample-based approach inferred the alpha value of pixels in unknown regions of the image by taking known pixel colours. The list of high fantasy tv shows https://artificialsflowers.com
