Towards No-Reference of Peak Signal to Noise Ratio [PDF]
El objetivo de este trabajo es definir un estimador de calidad de imagen perceptual no referenciado aplicando los conceptos perceptuales del Modelo de Inducción Cromática. El enfoque consiste en comparar la imagen recibida, presumiblemente degradada, con las versiones perceptuales (diferentes distancias) de esta imagen degradada por medio de un Modelo ...

Edge Detection Operators: Peak Signal to Noise Ratio Based Comparison [PDF]
Edge detection is the vital task in digital image processing. It makes the image segmentation and pattern recognition more comfort. It also helps for object detection. There are many edge detectors available for pre-processing in computer vision. But, Canny, Sobel, Laplacian of Gaussian (LoG), Robert's and Prewitt are most applied algorithms.
