This page contains information concerned with the stereo sequence "Cortile". We provide: the rectified stereo sequences, the disparity maps (for five settings 1, 2, ,4 , 8, 16 of the subpixel parameter) computed by the SMP stereo algorithm (settings for 320x240 resolution and settings for 640x480 resolution) and the parameters for obtaining the 3D depth measurements (see README files). Disparity maps are encoded with RGB images (saved with OpenCV) as described in the README file and below.

Two sequences (in bitmap file format) are available: background sequence ("bck") and moving people sequence.

Both sequences and disparity maps (for five settings 1, 2, ,4 , 8, 16 of the subpixel parameter) computed by the SMP stereo algorithm are available at 320x240 and 640x480 resolution.

A spreadsheet characterizing the stereo rig is also available here; the mandatory parameters of the spreadsheet are SCALE (SCALE=2 for 320x240 images and SCALE=1 for 640x480 images) and SUBPIXEL (1, 2, 4, 8, 16).

Valid disparity values for both sequences, resolutions and subpixel parameter are encoded with 16 bit (using 2 out of 3 RGB channels):

** Valid disparity **
Channel 0: Least significant byte
Channel 1: Most significant byte
Channel 3: 0

** Invalid disparity **
Channel 0: 0
Channel 1: 128
Channel 3: 255
