- We present an interactive scheme for processing of digital mammograms relying upon a steerable dyadic wavelet transform. Coefficients of the translation and rotation-invariant transform are interactively processed before an inverse transform is applied. Analysis is carried out at dyadic scales and along arbitrary orientations. Local orientation is computed at each level of scale and spatial position and formulated into criteria for including or excluding specific orientations for contrast enhancement and enhancing locally radiating structures. Transform coefficients that were selected for contrast enhancement are modified by a piecewise linear enhancement function. The presented scheme is flexible enough to enable efficient position, scale, and orientation based interactive processing and analysis.
