Stereo vision, resulting in the knowledge of deep information in a scene, is of great importance in the field of machine vision, robotics and image analysis. In this article, an explicit analysis of the existing stereo matching methods, up to date, is presented. The presented algorithms are discussed in terms of speed, accuracy, coverage, time consumption, and disparity range. Towards the direction of real-time operation, the development of stereo matching algorithms, suitable for efficient hardware implementation is highly desirable. Implementations of stereo matching algorithms in hardware for real-time applications are also discussed in details.

“…SAD-based algorithms are among the least complex and more often used. Census-based algorithms [29][30][31][32], first introduced in [33], are common in real-time hardware-based systems [34][35][36][37][38] and may work better in the homogeneous zones of the image. Its complexity increases when used in software-based systems because of its bit-based nature.…”

Stereoscopic 3D video quality assessment based on depth maps and video motion

et al. 2013

In this paper, we propose techniques to assess the objective quality for stereoscopic 3D video content, related to motion and depth map features. An analysis has been carried out in order to understand what causes the generation of visual discomfort in the viewer's eye when visualizing a 3D video. Motion is an important feature affecting 3D experience but is also often the cause of visual discomfort. Guidelines are obtained after applying the algorithm to quantify the impact over viewer's experience when common cases happen, such as high motion sequences, scene changes with abrupt parallax changes, or complete absence of stereoscopy.

“…These registers are also kept in buffers during the next processing round so that they can be reused during several clock periods (12, 13). Second the column SAD's from several processing rounds are summed to calculated the SAD values (9,10,11). For a 3x3 subwindow with a disparity range of 2; 9 AD calculations, 24 adders and 3 registers files with a size equal to the window width multiplied with the window height are needed.…”

Abstract-This paper presents a novel binary fully adaptable window for incorporating in a stereo matching System-on-Chip (SoC) architecture. This architecture is fully scalable and parameterizable to allow for custom SoC implementations, as well as rapid prototyping on FPGAs. For each window a binary mask window is generated which selects the supporting pixels in the cost aggregation phase of the SAD algorithm. This selection is performed using color similarity and spatial distance metrics. Hardware resource utilization for a fixed window and an adaptable window cost aggregation is compared based on FPGA logic element use.
