Gabor filter theory of communication

WebApr 1, 1998 · The Gabor filter is based on a multi-channel filtering theory for processing visual information in the early stages of the human visual systems. The performance of the Gabor-filter-based method is demonstrated on the ETL-1 database. WebDec 6, 2012 · In his paper Theory of Communication [Gab46], D. Gabor proposed the use of a family of functions obtained from one Gaussian by time-and frequency shifts. Each of these is well concentrated in time and frequency; together they are meant to constitute a complete collection of building blocks into which more complicated time-depending …

Webi.gabor computes texture raster maps from a user-specified Gabor filter bank and raster map. The 2 dimensional Gabor filter is an orientation sensitive filter which mimics the cells within the human visual cortex by creating a filter bank of multiple orientations and scales to pick up different frequency responses. Webwhere m x and m y define the center of the Gabor receptive field, σ x and σ y define its size, γ determines the preferred orientation, φ is a phase offset, and 1/λ is the preferred spatial frequency of the Gabor filter.
