Texton
The term ''texton'' was introduced by Béla Julesz in 1981 to describe "the putative units of pre-attentive human texture perception." The term reemerged in the late 1990s and early 2000s to describe vector quantized responses of a linear filter bank In signal processing, a filter bank (or filterbank) is an array of bandpass filters that separates the input signal into multiple components, each one carrying a single frequency Sub-band coding, sub-band of the original signal.

Béla Julesz
Béla Julesz (also Bela Julesz in English; February 19, 1928 – December 31, 2003) was a Hungarian-born American visual neuroscientist and experimental psychologist in the fields of visual and auditory perception. Julesz was the originator of random dot stereograms which led to the creation of autostereograms. He also was the first to study texture discrimination by constraining second-order statistics. Biography Béla Julesz was born in Budapest, Hungary, on February 19, 1928. He immigrated to the United States with his wife Margit after receiving his Ph.D. from the Hungarian Academy of Sciences in 1956. Although Béla is the Hungarian name with the accent, Julesz always used the non-accented version. In 1956, Julesz joined the renowned Bell Laboratories, where he headed the Sensory and Perceptual Processes Department (1964–1982), then the Visual Perception Research Department (1983–1989). Much of his research focused on physiological psychology topics including depth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filter Bank
In signal processing, a filter bank (or filterbank) is an array of bandpass filters that separates the input signal into multiple components, each one carrying a single frequency Sub-band coding, sub-band of the original signal. One application of a filter bank is a graphic equalizer, which can attenuate the components differently and recombine them into a modified version of the original signal. The process of decomposition performed by the filter bank is called ''analysis'' (meaning analysis of the signal in terms of its components in each sub-band); the output of analysis is referred to as a subband signal with as many subbands as there are filters in the filter bank. The reconstruction process is called ''synthesis'', meaning reconstitution of a complete signal resulting from the filtering process. In digital signal processing, the term ''filter bank'' is also commonly applied to a bank of receivers. The difference is that receivers also Digital down converter, down-convert t ...
