Method of enhancing the contrast of spatially-localized phenomena in an image

摘要

A kind of image for the spatially localized phenomenon improving contrast, such as Microcalcification is in mammogram, multi-resolution decomposition is applied to the image of digital signal representation to generate multiple detail images on different scale, and it is modified at least one scale that detail signal, which belongs to spatially localized phenomenon with common polarity (negative or positive),.
