IMPROVED DEVICE FOR PROCESSING IMAGES |
摘要 |
An image processing device comprises a store (110) for receiving image data (8) with a pixel identifier and at least one piece of associated intensity data and a pilot (100) which is provided to call a reduction unit (120) with pixels to be weighted and, for each pixel, in order to define a first neighborhood and a plurality of second neighborhoods with a neighborhood selection unit (130), in order to obtain a weighting value for the second neighborhood with a weighting unit (140) with the first neighborhood and a neighborhood among the plurality of second neighborhoods, in order to define each time a piece of weighted intensity data of a working pixel as the weighting value of the second neighborhood multiplied by the intensity data of the associated working pixel, and in order to define a piece of weighted intensity data of the pixel to be weighted by adding each of the pieces of weighted intensity data of a working pixel. The weighting unit (140) is provided to calculate the distance between first and second neighborhoods on the basis of a sum, where each square of the difference between the respective intensity data of these neighborhoods is modulated by a quantity which is inversely proportional to the intensity data in the second neighborhood.
