correlate params The following parameters can be accessed via the interactive dialogue box labeled Cor params:
Height, Width. Dimensions of correlation blocks.
Stretch, Compress. Defines the limits of the stretch algorithm. Both must be positive or zero, and compress should not be bigger than width/2.
Shear. Defines the range of values for the shear algorithm. This number, must be positive.
EDelta. During the creation of the output disparity, a compatibility criterion exists whereby an edge must be present, to within , when the disparity estimate is projected into the right image.
Range. The disparity search range. The search takes place over
, where initial is supplied by either the input disparity image or is estimated from the regions of interest.
CtF Scaling The stretch correlation algorithm is run initially on a down sampled version of both stereo images, inorder to home in on the solution which is consistent across scales. This choice menu determines the greatest level of down sampling used.
