Binarization is an important preprocessing step in several document image processing tasks. Binarization of historical document with poor contrast, strong noise, and non-uniform illumination is a challenging problem. A new binarization algorithm has been developed to address this problem. In this paper, we describe a new method which does not utilize statistical properties of the intensity hist...

A combination of phase-shift with gray-code light projection into a three-dimensional vision system based on the projection of structured light is presented. The gray-code method is exploited to detect without ambiguity even marked surface discontinuities, whereas the phase-shift technique allows the measurement of fine surface details. The system shows excellent linearity. An overall mean valu...

In this research paper we proposed a novel technique for detection of brain tumour by using brightness preserving dynamic fuzzy histogram equalization. The fuzzy histogram equalization uses fuzzy statistics of digital images for their representation. The technique enables to handles the imprecision of gray level value in better way resulting the highlight to hidden as well as blur part of the i...

Remote sensing images acquired in various spectral bands are used to estimate certain geophysical parameters or detect the presence or extent of geophysical phenomena. In a majority of cases, the raw image acquired by the sensor is processed using various operations such as filtering, compression, enhancement, etc. In performing these operations, the analyst is attempting to maximise the inform...

Title of Dissertation: ELECTROSTATIC MEMS ACTUATORS USING GRAY-SCALE TECHNOLOGY Brian Carl Morgan, Doctor of Philosophy, 2006 Dissertation directed by: Professor Reza Ghodssi Department of Electrical and Computer Engineering Institute for Systems Research The majority of fabrication techniques used in micro-electro-mechanical systems (MEMS) are planar technologies, which severely limits the str...

The message is the composition of some character. Every character of the message can be represented as an ASCII value, which is either even or odd. Depending on this evenness or oddness, the character is encrypted differently. This paper describes how such an even-odd encryption based on ASCII value is applied and how encrypted message converting by using Gray code and embedding with picture ca...

The paper presents techniques for the construction of invariant gray scale features. That are characteristics of gray scale images which remain constant if the images are transformed according to the action of a transformation group. We rst introduce a general method applicable to arbitrary transformation groups and specialize the results afterwards to the group of image rotations and translati...

The goals of this research were to estimate the phenotypic relationship among various breat meat quality traits, blood parameters and tonic immobility from a broiler and to describe the relation among these variables. Broiler chicks were devided into different groups: (1) colour clothing groups represented four different colours as red, blue, green, and gray and (2) the chicks that were subject...

In an attempt to mimic human (colorful) texture classification by a clustering algorithm three lines of research have been encountered, in which as test set 180 texture images (both their color and gray-scale equivalent) were drawn from the OuTex and VisTex databases. First, a k-means algorithm was applied with three feature vectors, based on color/gray values, four texture features, and their ...
