Simple cells in visual cortex area 1 and 2 (V1)  are known for their orientation selectivity and orientation tuning. The complex cells on the other hand respond well to at least some of the complex stimuli and explicitly represent complex shape information and suggest specific types of higher order visual information that V2 cells extract from visual scenes. In this work, mathematical models for simple and complex cells are presented. Using these models, a frame work for form detection was presented. 


The flow chart of the algorithm and the explanation is provided in the poster below.
