Detailed Description
Shrinker class to shrink ROIs.This shrinker shrinks a given ROI. This is done to cope with several special problems that arise in different setups. For example if playing downstairs in the lobby without a carpet we always have a problem with reflections on the floor.
This shrinker works like this:
- if ROI is vertically rectangular, we cut off the bottom part because it is likely to contain reflection
- if ball is not close (roi->width <= 100), we tighten the ROI, such that it only contains the ball. This helps against reflection. (If ball is close, this does not work, because it takes away too many edge pixels.)

Member Function Documentation
| void Shrinker::setFilteredBuffer | ( | unsigned char * | yuv422planar_buffer | ) | [virtual] |
Set the filtered buffer.
The buffer is assumed to being YUV422_PLANAR mode and the desired filter combination has been run.
- Parameters:
-
yuv422planar_buffer YUV422 planar buffer

| void Shrinker::shrink | ( | ROI * | roi | ) | [virtual] |
Shrink! Do the actual shrinking.
See above for used method.
- Parameters:
-
roi ROI to srhink
