In this work we propose a scanline optimization procedure
for computational stereo using a linear smoothness
cost model performed by programmable graphics hardware.
The main idea for an efficient implementation of this
dynamic programming approach is a recursive scheme to
calculate the min-convolution in a manner suitable for the
parallel stream computation model of graphics processing
units. Since many image similarity functions can be efficiently
calculated by modern graphics hardware, it is reasonable
to address the final disparity extraction by graphics
processors as well. Our timing results indicate that the proposed
approach is beneficial for larger image resolutions
and disparity ranges in particular.
