Abstract:
1. A computer-implemented method of enhancing a contrast of spatially localized phenomena in a medical image, the method comprising: applying a multi-scale decomposition to a digital signal representation of the medical image to generate detail images at different scales; after the multi-scale decomposition applying step, modifying detail signals in the detail images pertaining to the spatially localized phenomena having a first common polarity at at least one of the scales, a spatial extent of a region to which the modifying step is applied being limited to pixels within a neighborhood surrounding a position of the spatially localized phenomena, and the modifying step includes applying an amplification factor to the detail signals to be modified or applying a look up table operation to the detail signals to be modified; and leaving unchanged ones of the detail signals pertaining to the spatially localized phenomena having a second common polarity.
