METHOD, SYSTEM AND APPARATUS FOR APPLYING HISTOGRAM EQUALIZATION TO AN IMAGE |
摘要 |
A method for applying histogram equalization to an image comprises calculating a histogram of at least one image portion of an input image to obtain histogram data representing the number of occurrences of different brightness values in said at least one image portion. Said histogram data is filled up such that substantially all brightness values have a minimum number of occurrences. A cumulative distribution function is calculated from said filled up histogram data and is equalized in a predetermined range. Finally, said at least one image portion of the input image is remapped based on said equalized cumulative distribution function. |
