The sparse approach is chosen since the intention is not to reconstruct the entire disparity field but to find large range disparities in frames; as a byproduct, edge sparseness enables more rapid and efficient estimation of disparity statistics.
The sum of ranges, a range-based disparity metric, is more sensitive to sample size.
We observe that for sequences such as 'lovebird', 'pantomime'outdoor',r', the proposed method does not improve with respect to DISCOVER since they have a small range of disparity values; in such cases, using disparity to discriminate foreground and background is less successful.
The allowable range of disparity S d ={d min,⋯,d max}, the disparity of pixel p is dleft(p right) = argminlimits_{d in {S_{d}}} {C_{text{ASW} + text{nmi}}}(p,{p_{d}}). (5).
Within the allowable range of disparity S d ={d min,⋯,d max}, the disparity of pixel p is dleft(p right) = argminlimits_{d in {S_{d}}} {C_{text{NMI}}}left {N_{p}},{N_{{p_{d}}}}right).
The algorithm reduced the search range for disparity estimation based on a correlation between neighboring cameras and selectively skipped the motion estimation process through the use of the relationship between the motion and disparity vectors.
The module constantly estimates the precisely required range of disparity levels upon a given stereo image set, maintaining this range as low as possible by verging the stereo setup cameras axes.
The latter mechanism takes place within Panum's area, i.e., a small range of disparity where sensory fusion of the two retinal images is performed, thus avoiding double vision [9], [20].
For BLOCK, SEMI, CROSS this was calculated from the run time on a given image and disparity range.
This corresponds to the range of disparities for which apparent depth no longer increased with disparity for our stimuli, consistent with the idea of patent stereopsis occurring within the range of diplopia.
