Object Perception: Generative Image Models and Bayesian Inference [chapter]

Daniel Kersten
2002 Lecture Notes in Computer Science  
The visual system does this by integrating prior object knowledge with critical image features appropriate for each of a discrete number of tasks.  ...  However, formulating optimal theories for realistic vision problems is a non-trivial problem, and we can gain insight into visual inference by first characterizing the causal structure of image features-the  ...  When an observer is asked to match the surface color to the i th test patch, the optimal decision is based on P (ρ i 1 |C obs ), which is obtained by integrating out x and the confounding variable α from  ...

Active surface estimation: integrating coarse-to-fine image acquisition and estimation from multiple cues

Subhodev Das, Narendra Ahuja
1996 Artificial Intelligence  
This paper is concerned with the problem of surface reconstruction from stereo images for large scenes having large depth ranges with depth discontinuities.  ...  The passive stereo paradigm is inadequate for this problem because of the need to aim cameras in different directions and to fixate at different objects.  ...  A coarse estimate of the surface under reconstruction from focus was used by stere'o to predict matches for the surface features, generate depth points from the matches, and interpolate a more accurate  ...
