public class MultiSpectral<T extends ImageSingleBand> extends ImageMultiBand<MultiSpectral<T>>
An image class for images with multiple bands/colors where each band is stored as an independent
ImageSingleBand. MultiSpectral image fully supports all functions inside of
ImageBase. Each internal image has the same width, height, startIndex, and stride.
For example, in a RGB image there would be three bands one for each color,
and each color would be stored in its own gray scale image. To access the image for a particular
band call getBand(int). To get the RGB value for a pixel (x,y) one would need to:
int red = image.get(0).get(x,y); int green = image.get(1).get(x,y); int blue = image.get(2).get(x,y);Setting the RGB value of pixel (x,y) is done in a similar manor:
image.get(0).get(x,y,red); image.get(1).get(x,y,green); image.get(2).get(x,y,blue);
May image processing operations can be run independently on each color band. This is useful since many
operations have been written for ImageSingleBand, but not MultiSpectral yet.
for( int i = 0; i < image.numBands(); i++ ) {
SomeGrayImageFilter.process( image.getBand(0) );
