Probability theory and statistics are two main tools in signal and image processing. Bayesian inference has a privileged place in developing methods for inverse problems arising in signal and image processing which can be applied in real world applications. In this tutorial presentation, first I will breifly present the Bayesian estimation approach in signal and image processing. Then, I will s...
Image fusion is a method for obtaining a highly informative image by merging the relative information of an object obtained from two or more image sources of the same scene. The satellite cameras give a single band panchromatic (PAN) image with high spatial information and multispectral (MS) image with more spectral information. The problem exists today is either PAN or MS image is available fr...
In POCS image restoration we consider the case where the prototype images are obtained from the observed image via a predetermined operator, which is the Modified Inverse Filter. A POCS algorithm using the proposed constraints and the limited amplitude constraint is applied to monochrome CBERS-2 satellite band 2 images.
The goal of this study is to develop a customised computer model that can accurately represent the motion of vocal articulators during vowels and consonants. Models of the articulators were constructed as Finite Element (FE) meshes based on digitised high-resolution MRI (Magnetic Resonance Imaging) scans obtained during quiet breathing. Articulatory kinematics during speaking were obtained by E...
For advanced CMOS processes, inverse lithography promises better patterning fidelity than conventional mask correction techniques due to a more complete exploration of the solution space. However, the success of inverse lithography relies highly on customized cost functions whose design and know-how have rarely been discussed. In this paper, we investigate the impacts of various objective funct...
In this paper, we nd the relationships between module contractibility of aBanach algebra and its ideals. We also prove that module contractibility ofa Banach algebra is equivalent to module contractibility of its module uniti-zation. Finally, we show that when a maximal group homomorphic image ofan inverse semigroup S with the set of idempotents E is nite, the moduleprojective tensor product l1...
INTRODUCTION A novel image reconstruction technique, which avoids aliasing artifacts by scalable image reconstruction in Magnetic Resonance Imaging, is proposed. The signal obtained in the phase-scrambling Fourier imaging technique can be transformed to the signal described in the Fresnel transform equation of the objects. Therefore, image reconstruction can be performed not only by inverse Fou...
Bio-images such as fingerprint, face and iris are sensitive and hence small change in such images could affect the result substantially. The processing overhead could be reduced by encrypting a preferred region instead of encrypting the entire image. In this paper a novel fractional bio-image encryption method is presented using Karhunen-Loeve (KL) transform, which is a reversible linear transf...
