An improved prediction of DCT-based image filters efficiency using regression analysis
In the article efficiency of DCT-based filters for a wide-class of images is investigated. The study is carried out for additive white Gaussian noise (AWGN) case with several intensity levels. Local DCT-based filter is used as basic denoising technique.
The methods of image segmentation, a process of division of an image into different segments which contain pixels of similar color, are considered. Graph-based segmentation algorithm, which is based on Kruskal’s algorithm is implemented in C++ language.
