A new general methodology for Musical Pattern Discovery is proposed, which tries to mimic the flow of cognitive and sub-cognitive inferences that are processed when hearing a piece of music. A brief survey shows the necessity to handle such perceptual heuristics and to specify perceptual constraints on discoverable structures. For instance, successive notes between patterns should verify a spec...

A biologically-based neural network simulation is used to analyze the contributions to color perception of each of several processing steps in the visual system from the retina to cortical area V4. We consider the effects on color constancy and color induction of adaptation, spectral opponency, non-linearities including saturation and rectification, and spectrally-specific long-range inhibition...
