Abstract:
1. A method of enhancing the contrast properties of an input image included in input image data, comprising: analyzing the content of the input image or of another input image included in the image data and relating to the input image; calculating respective statistical properties or derivatives of the content of the input image relating to the input image; processing the calculated statistical properties or the derivatives; duplicating the input image data for receiving first and second duplicated input image data; calculating a histogram for the input image included in the first duplicated input image data; equalizing the input image included in the first duplicated input image data on the basis of the calculated histogram to obtain a corresponding histogram equalized image; and merging in dependency of a result of the processed calculated statistical properties or the derivatives the histogram equalized image and the input image included in the second duplicated input image data to obtain an output image; wherein the calculation of the statistical properties or the derivatives is performed in accordance with the content of the output image.
