Surround suppression is ubiquitous in visual processing and perception. Neurophysiology and modeling studies reveal a rich set of spatial context effects in the Primary Visual Cortex, whereby surrounding stimuli nonlinearly modulate (e.g., suppress) the responses of a center target stimulus. Studies suggest that the strength of surround suppression depends on the image statistics of the center and surround pattern. Namely, if the center and surround share similar statistics, the neural responses are more suppressed by the surround. This behavior has been connected to computational benefits suc
