Advanced Techniques for Noisy Image Quality Assessment

Quality assurance is probably the most common and most studied problem in image processing. The image is assumed to be corrupted by impulse noise. In this book, want to estimate the noise in a singly image is estimated using the PCA algorithm. The image is divided into segment and noise is estimated through Principal component analysis (PCA). Contour based approach is used for the segmentation of image. A model is proposed which is used it to estimate noise standard deviation in noisy image. The RGB model will be used for noise estimation from an image. The noise is removed through principal component analysis with contour-based segmentation. It provide the efficiency for estimate and removal of noise. This book provides an efficient segmentation technique for segmenting color images. It provides a good compromise between the accuracy and the execution time: it is much faster than the methods and considerably more accurate than the methods. The proposed quality assurance method can be efficiently used in various image applications such as digital cameras and is superior because of its performance and simplicity.
