In this contribution we report on an approach for dense matching, based on local optimization.  ...  The future tasks mainly include research on refinement of the disparity map and development of a self-adaptive approach for weighting the contribution of different matching cost components.  ...  Adaptive windows represent an attempt to find the optimal shape and size of a support region, often leading to windows of irregular shapes.  ...

An empirical comparison of real-time dense stereo approaches for use in the automotive environment

Filip Mroz, Toby P Breckon
2012 EURASIP Journal on Image and Video Processing  
A proposed solution is the use of adaptive shape areas chosen based on local colourise similarity to that of the anchor (i.e. centre) pixel (with assumption that the close surfaces of the same colour are  ...  An alternative method is based on adaptive weights corresponding to colour and distance of the supporting pixels to the anchor pixel.  ...

Recovering Stereo Pairs from Anaglyphs

Armand Joulin, Sing Bing Kang
2013 2013 IEEE Conference on Computer Vision and Pattern Recognition  
Our technique then iteratively refines the matches, selects the good matches (which defines the "anchor" colors), and propagates the anchor colors.  ...  We use a diffusion-based technique for the color propagation, and added a step to suppress unwanted colors. Results on a variety of inputs demonstrate the robustness of our technique.  ...  The work done by the first author was partially supported by the European Research Council (SIERRA and VIDEOWORLD projects).  ...

Time-Varying Surface Reconstruction of an Actor's Performance [chapter]

Ludovic Blache, Mathieu Desbrun, Céline Loscos, Laurent Lucas

Cue-selective adaptation operates on a separable encoding of stereo and texture information [article]

Evan Cesanek, Fulvio Domini
2019 bioRxiv   pre-print
At the end of each movement, the fingers closed down on a physical object consistent with one of the two cues, depending on the condition (haptic-for-texture or haptic-for-stereo).  ...  Overall, these experiments support a model of cue-selective adaptation driven by correlations between error signals and input values (i.e., supervised learning), rather than mismatched haptic and visual  ...  Acknowledgments 17 This work was supported by a National Science Foundation grant to F.

DAISY: An Efficient Dense Descriptor Applied to Wide-Baseline Stereo

E. Tola, V. Lepetit, P. Fua
2010 IEEE Transactions on Pattern Analysis and Machine Intelligence  
In this paper, we introduce a local image descriptor, DAISY, which is very efficient to compute densely.  ...  This yields much better results in wide-baseline situations than the pixel and correlation-based algorithms that are commonly used in narrowbaseline stereo.  ...  Its shape is closely related to that of [32] , which has been shown to be optimal for sparse matching but is not designed for efficiency.  ...
