Progress in stereo algorithm performance is quickly outpacing the ability of existing stereo data sets to discriminate among the best-performing algorithms, motivating the need for more challenging scenes with accurate ground truth information. This paper describes a method for acquiring high-complexity stereo image pairs with pixel-accurate correspondence information using structured light. Unlike traditional range-sensing approaches, our method does not require the calibration of the light sources and yields registered disparity maps between all pairs of cameras and illumination projectors. We present new stereo data sets acquired with our method and demonstrate their suitability for stereo algorithm evaluation. Our results are available at

    • "Scharstein et al. [32] developed an online evaluation platform which provides stereo datasets consisting of the image pair and the corresponding GT data. The datasets show indoor scenes and are created with a structured light approach [33]. Recently, an updated and enhanced version was presented which includes more challenging datasets as well as a new evaluation method [31]. "

    • "• Structured-light 3D scanners project an infrared structured-light pattern onto the scene. When projecting a pattern onto a three-dimensionally shaped surface, the observed pattern is geometrically distorted [79]. By comparing the expected projected pattern (if no object is in the scene) and the deformed observed pattern, exact geometric reconstruction of the surface shape can be recovered. "

    ABSTRACT: In recent years, there has been a proliferation of works on human action classification from depth sequences. These works generally present methods and/or feature representations for the classification of actions from sequences of 3D locations of human body joints and/or other sources of data, such as depth maps and RGB videos. This survey highlights motivations and challenges of this very recent research area by presenting technologies and approaches for 3D skeleton-based action classification. The work focuses on aspects such as data pre-processing, publicly available benchmarks and commonly used accuracy measurements. Furthermore, this survey introduces a categorization of the most recent works in 3D skeleton-based action classification according to the adopted feature representation. This paper aims at being a starting point for practitioners who wish to approach the study of 3D action classification and gather insights on the main challenges to solve in this emerging field.

    • "Most of the approaches for disparity ground truth calculation contain a step of smoothing or filling small wholes or noise-based artifacts to achieve a better quality disparity as the reference. It is suggested in[9]to use some interpolation method to fill small holes in the ground truth disparity. Akhavan et al.[10]manually filled in the holes in the reference disparity map caused by shadows. "

    ABSTRACT: Stereo matching under complex circumstances, such as low-textured areas and high dynamic range (HDR) scenes, is an ill-posed problem. In this paper, we introduce a stereo matching approach for real-world HDR scenes which is backward compatible to conventional stereo matchers. For this purpose, (1) we compare and evaluate the tone-mapped disparity maps to find the most suitable tone-mapping approach for the stereo matching purpose. Thereof, (2) we introduce a combining graph-cut based framework for effectively fusing the tone-mapped disparity maps obtained from different tone-mapped input image pairs. And finally, (3) we generate reference ground truth disparity maps for our evaluation using the original HDR images and a customized stereo matching method for HDR inputs. Our experiments show that, combining the most effective features of tone-mapped disparity maps, an improved version of the disparity is achieved. Not only our results reduce the low dynamic range (LDR), conventional disparity errors by the factor of 3, but also outperform the other well-known tone-mapped disparities by providing the closest results to the original HDR disparity maps.
