Abstract

We present a theory and algorithms of 2D multi-Gabor representations (2DMGR) using a set of nonseparable 2D window waveforms. These windows can be customized to have different spatial and frequency orientations, and different shapes and variances. Together, they form a frame in a 2D space. 2DMGRs have clear values in applications where different spatial and frequency contents and orientations of an image are important features, e.g., in texture analysis, synthesis and segmentations, and in studies of mammalian visual systems, etc.. Numerical recipe and simulation examples are also provided.
