Image deconvolution problem is a challenging task in the field of image process. In this paper, an improved wiener filtering algorithm is proposed to accurately restore the degraded image of optical sparse aperture systems (OSAS). Differing from Wiener filter which needs to estimate the ratio of power spectrum of noise to power spectrum of original image, our algorithm analyzes the relationship between...
Visual evoked potentials (VEPs) are electrical responses to visual stimuli aroused in the occipital region of the cerebral cortex. The P100 is an important component of VEP, and its latency is generally used for diagnosis of many clinical diseases. The existing methods to extract VEP have several drawbacks such as involving too many stimuli, costing too much time or requiring a large training database...
