According to the invention, the high-pass filter determines the correction (C,(Pr,r)) of each pixel (Pr,r; Px,x) on the basis of a mean of the intensities of at least pairs of pixels being next to, that is at predetermined distances from and on opposite sides of the filtered pixel...

Mean filter is used to remove the Gaussian noise from the image. Edge pixels are lost due to the mean filtering operation. Edges are preserved with the help of the specialized architecture. Preserved edges are recombined with mean filtered image to improve the image quality. Filter structure is...

Electromyography recordings were amplified (×100 for GM and TA, ×1,000 for PL; P511AC amplifiers, Grass), band-pass filtered (3 Hz to 3 kHz) and digitized with a PowerLab recording system (PowerLab16SP, ADInstruments) at 20 kHz. Data analysis The amplitude of each CMAP was ...
In auditory perception, a right hemisphere (RH)/left ear advantage(LEA) for low-pass filtered stimuli and a left hemisphere (LH)/right ear advantage(REA) for high-pass filtered stimuli have been reported. Here we investigated how tonal language experience modulates this hemispheric asymmetry. We...
Each focal plane of the corrected z-stacks was high-pass filtered to remove background, deconvolved to tighten RNA spots, and then Gaussian-pass filtered to facilitate connecting signals from one imaging round to another. To correct for differences in the brightness between color channels, images ...
