The problem of visibility improvement by means of television image processing is considered. Two main approaches to enhancement of images, recorded in adverse weather, are analyzed. As an example of model-based method the dark channel prior method was chosen. Its results are compared with results of nonlinear contrast enhancement methods. The modification of adaptive histogram equalization that supposes...
The method of correction of digital television images, recorded in bad weather, is presented. Adaptive histogram equalization was applied as the basis of the method.
The noise compensation method, which is applicable in high frequency systems, is presented. Noise compensation is realized by using of both channels of polar modulated signals.
The Long Term Evolution (LTE) network organization features were analyzed. Some engineering proposals for physical layer realization simplification are presented. The OFDM modem block diagram including directional diagram forming block for MIMO and Beamforming technologies is developed. The advantages of ring antenna arrays using for cell searching are shown.
The pre-processing of digital images within the framework of the general method of digital image restoration based on Wiener technique allowing us to obtain information about additive noise using distorted image is presented.
