IMAGE PROCESSING METHOD AND DEVICE FOR DETECTION AND EMPHASIS OF EDGE

摘要

PROBLEM TO BE SOLVED: To provide a technique for determining whether pixel in an image indicates a homogeneous tissue to which a smoothing algorithm should be applied.SOLUTION: After the direction and size of an edge calculated by an edge detection filter is supplied to a filter selection lookup table, either a two-dimensional image filter or a filter coefficient value corresponding to the two-dimensional image filter can be selected by the filter selection lookup table 263. A plurality of filter coefficients are downloaded from the LUT 263 to an image processing filter 261, and are applied to the original image so that an output image can be brought about based on one pixel.
