Image enhancement using the mean dynamic range maximization with logarithmic operations
Vasile Patrascu
In this paper we use a logarithmic model for gray level image enhancement. We begin with a short presentation of the model and then, we propose a new formula for the mean dynamic r…
Contour Detection Using Contrast Formulas in the Framework of Logarithmic Models
Vasile Patrascu
In this paper we use a new logarithmic model of image representation, developed in [1,2], for edge detection. In fact, in the framework of the new model we obtain the formulas for…
Image Enhancement Using a Generalization of Homographic Function
Vasile Patrascu
This paper presents a new method of gray level image enhancement, based on point transforms. In order to define the transform function, it was used a generalization of the homograp…

Vasile Patrascu
This paper presents a method for enhancing the gray level images. This method takes part from the category of point transforms and it is based on interpolation functions. The latte…
Gray level image enhancement using the Bernstein polynomials
Vasile Patrascu
This paper presents a method for enhancing the gray level images. This presented method takes part from the category of point operations and it is based on piecewise linear functio…
Image Dynamic Range Enhancement in the Context of Logarithmic Models
Vasile Patrascu, Vasile Buzuloiu
Images of a scene observed under a variable illumination or with a variable optical aperture are not identical. Does a privileged representant exist? In which mathematical context?…
The Affine Transforms for Image Enhancement in the Context of Logarithmic Models
Vasile Patrascu, Vasile Buzuloiu
The logarithmic model offers new tools for image processing. An efficient method for image enhancement is to use an affine transformation with the logarithmic operations: addition…
A Mathematical Model for Logarithmic Image Processing
Vasile Patrascu, Vasile Buzuloiu
In this paper, we propose a new mathematical model for image processing. It is a logarithmical one. We consider the bounded interval (-1, 1) as the set of gray levels. Firstly, we…
Color Image Enhancement In the Framework of Logarithmic Models
Vasile Patrascu, Vasile Buzuloiu
In this paper, we propose a mathematical model for color image processing. It is a logarithmical one. We consider the cube (-1,1)x(-1,1)x(-1,1) as the set of values for the color s…
An Algebraical Model for Gray Level Images
Vasile Patrascu
In this paper we propose a new algebraical model for the gray level images. It can be used for digital image processing. The model adresses to those images which are generated in i…
Neutrosophic information in the framework of multi-valued representation
Vasile Patrascu
The paper presents some steps for multi-valued representation of neutrosophic information. These steps are provided in the framework of multi-valued logics using the following logi…
