Image processing is any form of information processing in which both input and output are images. Most of the image processing involves in treating the image as two dimensional representations and applying standard techniques to it. Images contain lot of uncertainties and are fuzzy/vague in nature. Various fuzzy filtering techniques are defined for noise removal in image processing and these existing filters helps to enhance the image using only the membership values. Further, by incorporating intuitionistic fuzzy filters, vagueness and ambiguity are managed by taking the non-membership values also into consideration. In this paper, light is thrown on some important types of noise and a comparative analysis is done. This paper also presents the results of applying different noise types to an image and investigates the results of various intuitionistic fuzzy filtering techniques. A comparison is made on the results of all the techniques.

Difference Discretization

A method for nearly orthogonal grid generation is presented in this study. The generating system is based on solution of a system of partial differential equations with finite difference discretization. The grid quality control functions and grid properties are investigated. Specification of both boundary point distribution on all sides is used. The proposed method is applied to various test problems，which shows this method provides a good balance between controlling grid orthogonality and cell aspect ratio.

Particle Geometry

This paper describes a new approach to the direct numerical simulation of particle flows and illustrates its performance on several examples. The method uses a fixed regular orthogonal grid and combines an analytic solution, valid in the neighborhood of each particle, with a finite-difference solution away from the particle. In effect, the analytic solution is used to ‘transfer’ the boundary conditions at the particle surface to the neighboring grid nodes, thus eliminating the complexity arising from the incompatibility of the particle geometry with that of the underlying fixed grid. Furthermore, the hydrodynamic force and couple on the particle are computed directly with no need for the error-prone extrapolation or interpolation procedures necessary with other methods.

I should like to give you a very condensed progress report on some spectrophotometric measurements of objective-prism spectra made in collaboration with H. Leicher at Bonn. The procedure used is almost completely automatic. The measurements are made with the help of a semi-automatic fully digitized registering microphotometer constructed by Hög-Hamburg. The reductions are carried out with the aid of a number of interconnected programmes written for the computer IBM 7090, beginning with the output of the photometer in the form of punched cards and ending with the printing-out of the final two-dimensional classifications.
