Examining the Results

For all algorithms other than GaussClumps, the pixel values in the output NDF created by FINDCLUMPS and EXTRACTCLUMPS are integer values that indicate which clump each pixel belongs to (that is, all pixels that are contain within a single clump will all have the same integer value in the output NDF). Pixels that are not contained within any clump have bad values. For GaussClumps, each pixel value in the output NDF is the sum of the Gaussian models that contribute to that pixel.
