Data Set Overview : A Disparity file contains 2 bands of 32-bit floating point numbers in the Band Sequential order (line, sample). Alternatively, line and sample may be stored in separate single-band files. The parallax, or difference measured in pixels, between an object location in two individual images (typically the left and right images of a stereo pair) is also called the disparity. Disparity files contain these disparity values in both the line and sample dimension for each pixel in the reference image. This reference image is traditionally the left image of a stereo pair, but could be the right image for special products. The geometry of the Disparity image is the same as the geometry of the reference image. This means that for any pixel in the reference image the disparity of the viewed point can be obtained from the same pixel location in the Disparity image. The values in a Disparity image are the 1-based coordinates of the corresponding point in the nonreference image. Thus, the coordinates in the reference image are the same as the coordinates in the Disparity image, and the matching coordinates in the stereo partner image are the values is the Disparity image. Disparity values of 0.0 indicate no valid disparity exists, for example due to lack of overlap or correlation failure. This value is reflected in the MISSING_CONSTANT keyword. More information is found in ALEXANDERETAL2008, LEMMONETAL2007, and LEMMONETAL2008. Processing : This Operations RDR is produced by OPGS/MIPL using the Mars Suite of VICAR image processing software. Data : 2 bands, Float, DualPDS/VICAR (OPGS) binary file. Software : The MIPL Mars Program Suite was used to generate these RDRs. Media/Format : The data set will initially be delivered and kept online. Upon Mission completion, the SSI Operations RDRs will be delivered to PDS on DVD.
