示例1: Apply
static void Apply( GenericImage<P>& image, const LocalHistogramEqualizationInstance& instance )
{
if ( image.IsColor() )
{
Image L;
image.GetLightness( L );
L.Status() = image.Status();
Apply( L, instance );
image.Status() = L.Status();
image.SetLightness( L );
return;
}
// create copy of the luminance to evaluate histogram from
GenericImage<P> imageCopy( image );
imageCopy.EnsureUnique(); // really not necessary, but we'll be safer if this is done
size_type N = image.NumberOfPixels();
int numberOfThreads = Thread::NumberOfThreads( image.Height(), 1 );
int rowsPerThread = image.Height()/numberOfThreads;
image.Status().Initialize( "CLAHE", N );
AbstractImage::ThreadData data( image, N );
// create processing threads
ReferenceArray<LocalHistogramEqualizationThread<P> > threads;
for ( int i = 0, j = 1; i < numberOfThreads; ++i, ++j )
threads.Add( new LocalHistogramEqualizationThread<P>( data,
instance,
image,
imageCopy,
i*rowsPerThread,
(j < numberOfThreads) ? j*rowsPerThread : image.Height() ) );
AbstractImage::RunThreads( threads, data );
threads.Destroy();
image.Status() = data.status;
