  6. 4. Imaging vision : functional mapping of intermediate visual processes in man

    Author : Jonas Larsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The human visual system is highly adept at recognizing objects independent of changes in viewing conditions, such as viewpoint, illumination, and partial occlusions by other objects in the visual environment. This invariance to viewing conditions is believed to be achieved by generating invariant shape representations from the variable visual input. READ MORE
