摘要
The present invention discloses a method and apparatus for enhancing image contrast using local histogram smoothing based on a multi-layer overlap block. According to another aspect of the present invention, there is provided a method for enhancing an image local contrast, comprising: converting brightness values of an input image according to multiple layers and generating multi-layer images having brightness values; Reducing noise of multi-layer images; And generating an enhanced local contrast image using the noise-reduced multi-layer images. According to the present invention, an image having improved image quality can be obtained as compared with the conventional algorithm.
