Physiological studies have revealed that the center–surround mechanism widely exists in
the primary stages of the human visual system, such as the retina, lateral geniculate nucleus …

Contour is a very important feature in biological visual cognition and has been extensively
investigated as a fundamental vision problem. In connection with the limitations of …

In the mammalian primary visual cortex, the response of the classical receptive field (CRF) to
visual stimuli can be suppressed by inhibition of non‐CRF (nCRF) neurons. Although many …

At the single-cell level in the visual system, the properties of the receptive field (RF) are
important bases of visual information processing. The area surrounding classical receptive …

In this paper, we present an optimized version of 1D-HMM for real-time face verification.
DCT coefficients of face images are used as observation vectors in HMM states. Three …
