IMVRegionOfInterest
The IMVRegionOfInterest interface offers methods to control
the ROIs (Region Of Interest) of a filters algorithm on a
MontiVision image processing filter. Most of the MontiVision
image processing filters allow to set a region of interest on the
input and output pin. Be sure to set equal input and output ROIs,
if you want to see the processed region at its original
position. Some filters also support a channel of interest
processing. COIs allow to process a selected color channel of an
image, for example if you only modify the red pixel in an RGB
image. Read the remarks
for implementation details.
