A New Approach to Image Enhancement by Non-Linear Contrast Stretching

摘要

This paper looks at the challenge of creating new, effective ways to improve images that are intended for use in mobile applications. The purpose of this study is to improve the efficiency of enhancing images in a fully automatic mode by parameter-free image intensity transformation. This paper proposes a new approach to enhancing the image by adaptively transforming its intensity based on the analysis of brightness distribution at the boundaries of the objects of this image. To demonstrate the possibilities of this approach, new techniques of intensity transformation are proposed. The proposed techniques provide effective image enhancement without the appearance of distortion and artifacts and are focused on use in mobile applications.
