A fast method for highresolution stereo matching without exploring the full search space. Plane hypotheses are generated from sparse feature matches. Around each plane, a local plane sweep with +/ 3 disparities levels is performed to establish local disparity hypotheses via SGM using NCC matching costs. Finally, each pixel is assigned to one hypothesis using global optimization, again using SGM.

Anonymous. Using local cues to improve dense stereo matching. CVPR 2015 submission 973.
In stereo matching cost filtering methods and energy minimization algorithms are considered as two different techniques. Due to their global extend energy minimization methods obtain good stereo matching results. However, they tend to fail in occluded regions, in which cost filtering approaches obtain better results. In this paper we intend to combine both approaches with the aim to improve overall stereo matching results.
We propose to perform stereo matching as a twostep energy minimization algorithm. We consider two MRF models: a fully connected model defined on the complete set of pixels in an image and a conventional locally connected model. We solve the energy minimization problem for the fully connected model, after which the marginal function of the solution is used as the unary potential in the locally connected MRF model.
Only gradient component (6D vector) of color images is used

This approach triangulates the polygonized SLIC segmentations of the input images and optimizes a lowerlayer MRF on the resulting set of triangles defined by photo consistency and normal smoothness. The lowerlayer MRF is solved by a quadratic relaxation method which iterates between PatchMatch and Cholesky Decomposition. The lowerlayer MRF is assisted by a upperlayer MRF defined on the set of triangle vertices which exploits local 'visual complexity' cues and encourages smoothness of the vertices' splitting properties. The two layers interact through an Alignment energy term which requires triangles sharing a nonsplit vertex to have their disparities agree on that vertex. Optimization of the whole model is iterated between optimizations of the two layers till convergence where the upperlayer can be solved in closed form.

Compute the matching cost with a convolutional neural network (accurate architecture). Then apply crossbased cost aggregation, semiglobal matching, leftright consistency check, median filter, and a bilateral filter.
DETAILS:
The network is similar to the one described in our CVPR paper differing only in the values of some hyperparameters. The input to the network are two 11 x 11 image patches. Five convolutional layers with 3 x 3 kernels and 112 feature maps extract feature vectors from the input image patches. The two 112length feature vectors are concatenated into a 224length vector which is passed through three fullyconnected layers with 384 units each. The final (fourth) fullyconnected layer projects the output to a single numberthe matching cost. One important addition was the use of data augmentation techniques to increase the size of the training set. We tried to use as much training data as possible. Therefore we combined all of the 2001, 2003, 2005, 2006, and 2014 Middlebury datasets obtaining 60 image pairs. For the newer datasets (2005, 2006, and 2014) we also used several illumination and exposure settings.
A prior disparity image is calculated by matching a set of reliable support points and triangulating between them. A maximum aposterior approach refines the disparities. The disparities for the left and right image are checked for consistency and disparity segments below a size of 50 pixels removed. (Improved results as of 9/14/2015 due to bug fix in colortogray conversion.)

S. Fang and Y. Li. Removed based multiview stereo using windowbased matching method. Submitted to MV&A, 2015.
Removed erroneous corresponding points from stereo pair and only correct corresponding points are kept which are obtained by NCC.
The method generates multiple proposals on absolute and relative disparities from multisegmentations. The proposals are coordinated by pointwise competition and pairwise collaboration within a MRF model. During inference, a dynamic programming is performed in different directions with various step sizes.
We postprocess the depth maps produced by Zbontar & LeCun's MCCNN technique. We use a domain transform to compute an edgeaware variance measure of our confidence in the depth map, and then run our robust bilateral solver on that depth map and confidence with a GemanMcClure loss function.
The MCCNN is computed using the publiclyavailable implementation (https://github.com/jzbontar/mccnn) which using the GPU, and the robust bilateral solver is computed using our CPU implementation which does not use the GPU, and is written in vanilla C++.

Anonymous. Imageguided nonlocal dense matching with threesteps optimization. ISPRS Congress 2016 submission 231.
This paper proposes a new imageguided nonlocal dense matching method with a threestep optimization based on the combination of imageguided methods and energy functionguided methods.

Window Size: 5
Weighting Coefficient: 0.3
Truncation Threshold (Census): 15
Truncation Threshold (HOG): 1
Imageguided Nonlocal Matching:
Smooth Term: 6
Penalty Term P1: 0.3
Penalty Term P2: 3
Disparity Interpolation:
Truncation Threshold: 5
Smooth Term: 3
Penalty Term P1: 3
Penalty Term P2: 30
Function Base: 5
An efficient stereo matching algorithm, which applies adaptive smoothness constraints using texture and edge information, is proposed in this work. First, we determine nontextured regions, on which an input image yields flat pixel values. In the nontextured regions, we penalize depth discontinuity and complement the primary CNNbased matching cost with a colorbased cost. Second, by combining two edge maps from the input image and a preestimated disparity map, we extract denoised edges that correspond to depth discontinuity with high probabilities. Thus, near the denoised edges, we penalize small differences of neighboring disparities.
The method uses the MCCNN code for the matching cost computation only.
Compute the matching cost with a convolutional neural network (fast architecture). Then apply crossbased cost aggregation, semiglobal matching, leftright consistency check, median filter, and a bilateral filter.

Anonymous. LSELAS: line segment based efficient large scale stereo matching. ICRA 2017 submission 289.
Our approach is an extension of the ELAS (from Geiger et al.) algorithm. We extract edges and sample our candidate support points along them. For every two consecutive valid support points we create a (straight) line segment. We force the triangulation to include the set of line segments (constrained Delaunay) for a better preservation of the disparity discontinuity at the edges.
Parameters as in the original ELAS algorithm.
For sampling candidate support points along the edge segments:
Adaptive sampling activated:
step = ceil(sqrt(img_diag)*0.5);
sampler(sqrt(step) / 2, step / 2, step / 2);
Anonymous. Morphological processing of stereoscopic image superimpositions for disparity map estimation. ECCV 2016 submission 1308.
The computation of the sparse disparity maps is achieved by means of a 3D diffusion of the costs contained in the disparity space volume. The watershed segmentations of the left and right views control the diffusion process and valid measurements are obtained by crosschecking.
The estimation of the dense disparity maps uses the sparse measurements as control points and is driven by a 3D watershed separating the disparity space volume into foreground and background pixels.

Shahbazi et al. Revisiting intrinsic curves for efficient dense stereo matching. ISPRS Congress 2016 submission 913.
No post processing (no filtering, no holefilling, no interpolation) performed.
The concepts of intrinsic curves were revisited and used for:
 disparity search space reduction, resulting in 83% reduction of the disparity range (individually for each pixel) directly from the original resolution of the image without needing hierarchical search
 reducing the ambiguities due to occluded pixels by integrating occlusion clues explicitly into the global energy function as a soft prior
The final energy minimization was done using semi global approach along eight paths.

H. Park and K. Lee. Look wider to match image patches with convolutional neural network. Submitted to IEEE Signal Processing Letters, 2016.
A novel pooling scheme is used to train a matching cost function with a CNN. It widens the size of receptive field effectively without losing the fine details.
The overall postprocessing pipeline is kept almost same as the original MCCNNacrt, except that the parameter settings are changed as follows:
cbca_num_iterations_1 = 0, cbca_num_iterations_2 = 1, sgm_P1 = 1.3, sgm_P2 = 17.0, sgm_Q1 = 3.6, sgm_Q2 = 36.0, and sgm_V = 1.4.

P. Knöbelreiter, C. Reinbacher, A. Shekhovtsov and T. Pock. Endtoend training of hybrid CNNCRF models for stereo. CVPR 2017.
We propose a novel method for stereo estimation, combining advantages of convolutional neural networks (CNNs) and optimizationbased approaches. The optimization, posed as a conditional random field (CRF), takes local matching costs and consistencyenforcing (smoothness) costs as inputs, both estimated by CNN blocks. To perform the inference in the CRF we use an approach based on linear programming relaxation with a fixed number of iterations. We address the challenging problem of training this hybrid model endtoend. We show that in the discriminative formulation (structured support vector machine) the training is practically feasible. The trained hybrid model with shallow CNNs is comparable to stateoftheart deep models in both time and performance. The optimization part efficiently replaces sophisticated and not jointly trainable (but commonly applied) postprocessing steps by a trainable, wellunderstood model.
