WebFrom experimentation, it is known that Gabor filters are a reasonable model of simple cells in the Mammalian vision system. Because of this, Gabor filters are thought to be a good model of how humans distinguish texture, and are therefore a useful model to use when designing algorithms to recognize texture. Web1.2 Gabor Energy Filters The real and imaginary components of a complex Gabor filter are phase sensitive, i.e., as a consequence their response to a sinusoid is another sinusoid (see Figure 1.2). By getting the magnitude of the output (square root of the sum of squared real and imaginary outputs) we can get a response that phase insensitive ...
