This paper addresses the problem of creation of new advanced technologies of image enhancement aimed at use in real-time mobile applications. The aim of this work is to increase the efficiency of image contrast enhancement by gray-level transformations. In order to achieve this aim, we propose a new approach to images enhancement based on an estimate of the brightness distribution at the boundaries of objects in the image. To demonstrate this approach proposes a new parameter-free technique of gray-level transformation for adaptive nonlinear image contrast stretching in automatic mode. The results of experimental research using known noreference metrics of contrast confirm the effectiveness of the proposed approach.
