Over the last three decades there has been significant progress in computer vision: it can now be used successfully for specific problems over many application areas. However, limited progress has been achieved on cognitive tasks such as general recognition (i.e. categorization) and scene understanding. Even given its successes, the remarkable abilities of human visual perception are currently still far beyond those of machine vision. These abilities are based in part on generic processes for image analysis, including powerful segmentation and figure-ground processes, colour constancy, the ability to estimate the 3D shape of objects using a variety of cues, etc. Human visual perception is equally remarkable for the largely unconscious mobilisation of knowledge about what the image means, or connotes. It has become clear that the processes of image analysis, memory (knowledge), and reasoning are closely inter-woven in the process that we call perception ...
