... To explain the impact of wavelets for lowlevel vision, we concentrate on three major applications: multiresolution processing, multiscale edge detection, and texture discrimination. Multiresolution algorithms modify the image resolution to p...
Wavelets, vision and the statistics of natural scenes
The processing of spatial information by the visual system shows a number of similarities to the wavelet transforms that have become popular in applied mathematics. Over the last decade, a range of studies have focused on the question of ‘why...

The continuous Wagon Wheel Illusion is object-based
The occurrence of perceived reversed motion while observers view a periodic, continuously moving stimulus (the “continuous Wagon Wheel Illusion”) has been taken as evidence that some aspects of motion perception rely on discrete sampling ...
