Synthesis of visual textures and perceptual asymmetry of visual texture perception

A new simple scheme is proposed to synthesize visual textures with positional jitter and/or orientation randomness that find extensive use in controlled psychophysical experiments for modelling (human) preattentive vision. Spectral properties of synthesized textures are then analyzed with the goal of creating a framework for computing signal-to-noise ratio from the spectral that offers the potential to interpret quantitatively certain perceptual phenomena, such as perceptual asymmetry.
