Cognitive SystemsForesight

• What are the potential implications of computer vision research for the study of biological vision, in areas other than 3D perception?

• Methods of representation• Does the brain develop a representation?

• Understanding/modelling the statistics involved• Theory of object recognition

• Are there general purpose computational/biological vision systems?• Biological systems appear to possess fixation?

• Mapping and path planning

• Additional questions:• Does the brain perform matrix multiplication? • Does the brain need a geometric model (a

coordinate system) for image recognition? 2D? 3D?• What is the purpose of vision?

• More generally, what are the potential influences from the study of computational cognitive systems on the study of biological ones?

• Learning how the brain builds models of objects/environments• How to model moving versus stationary objects• Do biological representations follow the laws of geometry?

• If so, how do they scale?• How to integrate biological models built at different

times, orientations, or locations• Does the brain keep our representations?

• If so, how does it use them?• Mosaic of environment

• What are the potential applications for society of the study of biological or computational vision systems?

• Biomedical imaging applications• Helping the blind: visual prostheses, visual preprocessors• Vehicle guidance, autonomous robots• Gesture recognition, multimedia systems• Neuropsychology:

• How do some pathologies disrupt the understanding of the meaning of objects?

• Can we learn about vision mechanisms from studying faulty systems?• Object/face recognition• Entertainment industry:

• Artificial actors, computer games• Surveillance: scene comprehension• Cybernetics: bionic man!
