Linear correction of YCbCr channels.
The filter operates in YCbCr color space and provides with the facility of linear correction of its channels - mapping specified channels' input ranges to specified output ranges.
The filter accepts 24 and 32 bpp color images for processing.
Sample usage:
// create filter YCbCrLinear filter = new YCbCrLinear( ); // configure the filter filter.InCb = new Range( -0.276f, 0.163f ); filter.InCr = new Range( -0.202f, 0.500f ); // apply the filter filter.ApplyInPlace( image ); Initial image:
Result image:
private void SetFilter()
{
ImageType = ImageTypes.Rgb32bpp;
Af.YCbCrLinear newFilter = new Af.YCbCrLinear();
newFilter.InY = yIn.ToIntRange(0, 255);
newFilter.OutY = yOut.ToIntRange(0, 255);
newFilter.InCb = cbIn.ToIntRange(0, 255);
newFilter.OutCb = cbOut.ToIntRange(0, 255);
newFilter.InCr = crIn.ToIntRange(0, 255);
newFilter.OutCr = crOut.ToIntRange(0, 255);
imageFilter = newFilter;
}
// On Filters->YCbCr filtering
private void yCbCrLinearFiltersItem_Click(object sender, System.EventArgs e)
{
YCbCrLinear filter = new YCbCrLinear();
filter.InCb = new Range(-0.3f, 0.3f);
ApplyFilter(filter);
yCbCrLinearFiltersItem.Checked = true;
}
