2013-10-10 07:53:29 -0600 | asked a question | Region of interest of YV12 matrix I have the following matrix in YV12 colorspace (stored as 1-channel image). It's filled with data which came from Android camera preview. Is it possible to extract some sub-region of this image (first step) and convert it to RGB colorspace subsequently (second step)? I would like to extract region first in order to keep good performance when converting. To say, I want to extract the following rect: Thanks in advance. |
