Pixon-Based Image Restoration/Reconstruction
This lecture introduces pixon-based image restoration/reconstruction methods. The relationship between image Algorithmic Information Content and the Bayesian incarnation of Occam's Razor are discussed as well as the relationship of multiresolution pixon languages and image fractal dimension. Also discussed is the relationship of pixons to the role played by the Heisenberg uncertainty principle ...
متن کاملThe Pixon Method of Image Reconstruction
The Pixon method is a high-performance, nonlinear image reconstruction method that provides statistically unbiased photometry and robust rejection of spurious sources. Relative to other methods, it can increase linear spatial resolution by a factor of a few and sensitivity by an order of magnitude or more. All of these benefits are achieved in computation times that can be orders of magnitude f...
متن کاملPixon-Based Multiresolution Image Reconstruction and the Quantification of Picture Infromation Content
This paper reviews pixon-based image reconstruction, which in it current formulation uses a multiresolution language to quantify an image's Algorithmic Information Content (AIC) using Baye-sian techniques. Each pixon (or its generalization, the informaton) represents a fundamental quanta of an image's AIC, and an image's pixon basis represents the minimum degrees-of-freedom necessary to describ...
متن کاملA Pixon-based Image Segmentation Method Considering Textural Characteristics of Image
Image segmentation is an essential and critical process in image processing and pattern recognition. In this paper we proposed a textured-based method to segment an input image into regions. In our method an entropy-based textured map of image is extracted, followed by an histogram equalization step to discriminate different regions. Then with the aim of eliminating unnecessary details and achi...
متن کاملA Novel Pixon-Based Image Segmentation Process Using Fuzzy Filtering and Fuzzy C-mean Algorithm
Image segmentation, which is an important stage of many image processing algorithms, is the process of partitioning an image into nonintersecting regions, such that each region is homogeneous and the union of no two adjacent regions is homogeneous. This paper presents a novel pixon-based algorithm for image segmentation. The key idea is to create a pixon model by combining fuzzy filtering as a ...
