摘要： A method for removing noise on a pixel by pixel basis from pixels of a digital image is disclosed. The pixels are used to produce a map of features, which then are used to produce a variable shape neighborhood region of cleaning pixels with respect to the original value of the pixel of interest. The neighborhood region of cleaning pixels and the value of the pixel of interest are then used to change the original value of the pixel of interest in the digital image so that it has been noise cleaned.

The apparatus includes a memory for storing the digitized image signal and a processor operative with the memory for generating an appropriate color value missing from a photosite location by the interpolation of an additional color value for such photosite locations from color values of different colors than the missing color value at nearby photosite locations. The processor also includes structure for obtaining Laplacian second-order values, gradient values and color difference bias values in at least two image directions from nearby photosites of the same column and row and for adding the Laplacian second-order values, gradient values and color difference bias values to define a classifier and for selecting a preferred orientation for the interpolation of the missing color value based upon a classifier. Finally, a arrangement is provided for interpolating the missing color value from nearby multiple color values selected to agree with the preferred orientation.
