Using V1-based models for difference perception and change detection

Using V1-based models, it is possible to investigate the features of human visual processing that influence difference perception and change detection. V1-based models were built based on the same basic constructs of the human visual system, incorporating mechanisms of visual processing such as colour opponency, receptive field tuning, contrast sensitivity, linear and non-linear behaviour, and response pooling. Three studies were conducted to investigate the use of such models in difference perception and change detection. These studies demonstrate the various applications of human vision models and highlight several key considerations that need to be made when using them.
