Analysis and Synthesis of Signals and Images


Mathematical bases of an integral operator for differentiating 2D images in order to increase their contrast are presented. Images are formed by an optic-electronic device under different background conditions. It is proven that the operator suppresses high-frequency components of images, generated by an applicative background and additive noise of the device. The universal property of the operator is determined, from which the known key differentiation operators are derived: gradient, Roberts, and Laplace operators. The results of contrasting real images by the proposed operator are presented.
