Most research in perception has been focused on the visual system, investigating the mechanisms of how we see and understand objects. A critical function of our visual system is its ability to recognize patterns, but the mechanism by which this is achieved is unclear. The earliest theory that attempted to explain how we recognize patterns is the template matching model. According to this model, we compare all external stimuli against an internal mental repre… WebIn the way of feature analysis, Pandemonium model divides the recognition process into four levels, each level has some “Demon” to perform a specific task, these “Demon” work in a hierarchical order. The first level is the image of stimuli encoded by “Image demon”. synchronized and unsynchronized in java
