WebJul 9, 2024 · The Gabor filter is a linear filter whose kernel is similar to the 2D receptive field profiles of the mammalian cortical simple cells (Tai 1996 ). It is considered a very useful tool in computer vision and image analysis because of its optimal localization properties in both spatial analysis and the frequency domain (Fazli et al. 2009 ). WebGabor applied ideas from quantum physics to sound, allowing an analogy between sound and quanta. He proposed a mathematical method to reduce Fourier analysis into cells. His research aimed at the information transmission through communication channels. Gabor saw in his atoms a possibility to transmit the same information but using less data.
