Stereo images rectification and disparity: which algorithms?
- by alessandro.francesconi
I'm trying to figure out what are currently the two most efficent algorithms that permit, starting from a L/R pair of stereo images created using a traditional camera (so affected by some epipolar lines misalignment), to produce a pair of adjusted images plus their depth information by looking at their disparity.
Actually I've found lots of papers about these two methods, like:
"Computing Rectifying Homographies for Stereo Vision" (Zhang - seems one of the best for rectification only)
"Three-step image recti?cation" (Monasse)
"Rectification and Disparity" (slideshow by Navab)
"A fast area-based stereo matching algorithm" (Di Stefano - seems a bit inaccurate)
"Computing Visual Correspondence with Occlusions via Graph Cuts" (Kolmogorov - this one produces a very good disparity map, with also occlusion informations, but is it efficient?)
"Dense Disparity Map Estimation Respecting Image Discontinuities" (Alvarez - toooo long for a first review)
Anyone could please give me some advices for orienting into this wide topic?
What kind of algorithm/method should I treat first, considering that I'll work on a very simple input: a pair of left and right images and nothing else, no more information (some papers are based on additional, pre-taken, calibration infos)?
Speaking about working implementations, the only interesting results I've seen so far belongs to this piece of software, but only for automatic rectification, not disparity: http://stereo.jpn.org/eng/stphmkr/index.html
I tried the "auto-adjustment" feature and seems really effective. Too bad there is no source code...
