Low level vision addresses the issues of labelling and organising image pixels according to scene related properties - known as intrinsic images - such as motion, contrast, relief, texture and reflectance. Such properties are hard to capture by hand-constructed models, and so there has been a considerable movement towards specifying them "generatively": models involving cascades of random variables are constructed as explanations of images. Details of the models are filled in by learning parameters from labelled training data. New inference algorithms such belief propagation, variational inference, particle filtering, min cut and others are used to apply these models to image analysis. Already some very promising results have been obtained, for example in segmentation, in stereo vision and in analysis of texture. This workshop will be a forum for some of the latest results and thinking in this area to be presented and explored.
