Fig. 6From: Spatial and spectral regularization to discriminate tissues using multispectral photoacoustic imagingEach step of the results. a Background noise suppressed by thresholding (for each pixel, the maximum noise amplitudes over all of the wavelengths is shown). b Output of the spatio-spectral mean-shift algorithm. c Two-dimensional map obtained, keeping only the P largest labeled areas. Unlabeled pixels are in black (label sets to zero)Back to article page
