Automatic Systems to fluid flow visualization can help in solution of several Fluid Dynamic Phenomena. Usually, these systems can be concerned of three fundamental steps: data acquisition, processing and result display. There are several ways to achieve the first step, which can be grouped as follows: simulation of mathematics elements, and detection/description of fluid flow patterns character...

The paper describes a method for the analysis of the content of a binary image in order to find its structure. The class of images it deals with consists of images showing a groups of objects connected one to another forming a graph-like structure. Proposed method extracts automatically this structure from image bitmap and produces graph adjacency matrix describing it. The method is based on mo...

Optical Coherence Tomography (OCT) technology introduces speckle, an insidious form of multiplicative noise which degrades the quality of OCT images. In this paper order statistics filters like Mean, Median, Min, Max and Alpha Trimmed Mean are implemented on digital image and OCT images. The images were tested with two different mask sizes of 5*5 and 7*7. The objective evaluation of both the ty...

We describe a new approach to lossy compression of silhouettelike images. By a silhouette-like image we mean a bi-level image consisting of black and white regions divided by a small number of closed curves. We use a boundary detection algorithm to express the closed curves by chain codes, and we express the chains as one function of one variable. We compress this function using WFA over two le...

This paper proposes algorithms for the analysis of sets of confocal microscope images of human brain tissue which constitute a 3D volume. The identification of suitable features for curve-like structures in these volumes is required for subsequent classification. The final goal is the distinction between brain tissues of patients with different degrees of neurological deceases. The given volume...

We propose to modify image inpainting technique based on F-transform for application dedicated to cartoon images. The images have typical features which are taken into consideration. These features make original algorithm ineffective, because of its isotropic nature. Proposed modification changes it to an anisotropic.
