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…
Gray Level Image Enhancement Using Polygonal Functions
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?…
