Figure 3From: An improved sparse representation model with structural information for Multicolour Fluorescence In-Situ Hybridization (M-FISH) image classificationThe schematic diagram of neighbouring region. Each square represents a pixel in an M-FISH image, corresponding to five channel spectral information. The y5 is a central pixel surrounded by its eight neighbouring pixels y1,y2,y3,y4,y6,y7,y8 and y9. The size of the neighbouring pixels can vary.Back to article page
