Subject: Convert disparity to CV_8UC1 and scale down to 1/16
X-Git-Tag: submit/tizen/20220701.002357~1^2~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9494c8911dada1eb7f7a745e0017a424fe5143ab;p=platform%2Fcore%2Fmultimedia%2Fdfs-opencv.git

Convert disparity to CV_8UC1 and scale down to 1/16

SGBM outs disparity map as CV_16SC type after scaling up 16 times.
To dump and check disparity results, convert them CV_8UC1 and
scale down to 1/16.
