Outdoor scene classification is challenging due to irregular geometry, uncontrolled illumination, and noisy reflectance distributions. This paper discusses a Bayesian approach to classifying a color image of an outdoor scene. A likelihood model factors in the physics of the image formation process, the sensor noise distribution, and prior distributions over geometry, material types, and illumin...

Colour image segmentation based on the hue component presents some problems due to the physical process of image formation. One of that problems is colour clipping, which appear when at least one of the sensor components is saturated. We have designed a system, that works for a trained set of colours, to recover the chromatic information of those pixels on which colour has been clipped. The chr...

historical memory or collective memory, in studies on cultural history and history of ideas, is often neglected. it is sufficient, for example, look at the names and titles to learn of the common view of a nation. this is true about alexander’s image in our culture. in our culture and some others, alexander is a myth and sometimes a unique hero. shahnameh can demonstrate this historical memory ...
