【Other】 mypsnr DL : 0: PSNR是最普遍，最广泛使用的评鉴画质的客观量测法，不过许多实验结果都显示，PSNR的分数无法和人眼看到的视觉品质完全一致，有可能PSNR较高者看起来反而比PSNR较低者差。这是因为人眼的视觉对于误差的敏感度并不是绝对的，其感知结果会受到许多因素的影响而产生变化-PSNR is the most common and most widely used uation of objective quality measurement method, but many experimental results show that the scores can not be exactly the same PSNR and visual quality of the human eye, it may look rather than the higher PSNR PSNR lower difference. This is because the human visual sensitivity to errors is not absolute, its perception of the results can be affected by many factors arising changes

【source in ebook】 ijabr201605104_Aryan DL : 0: Edge detection is widely used in image processing, image recognition and computer vision. Tradition edge detection methods have a lot of disadvantages. This paper presents a new edge detection algorithm base on Matching Pursuit (MP). Our method has four steps. Firstly, the color image is converted to gray Image. Secondly, the residual part of Matching Pursuit algorithm with the Wavelet Packet dictionary is extracted. Thirdly, the Gaussian Filter is applied to remove the additional parts of the previous image and finally, the Ostu’s thresholding method converts image to binary form. We compared our algorithm with the tradition methods like Prewitt, Sobel, Laplacian of Gaussian (LOG) and Canny operators. Results show that our algorithm has high value of Performance parameters such as PR, PSNR and FOM compared to other algorithms.
