Figure 1From: A simple mathematical model utilizing topological invariants for automatic detection of tumor areas in digital tissue imagesThe schematic illustration. Left: the number of solid components b0 =7 and the number of windows b1=0, then the ratio b1/b0=0/7=0, Right: the number of solid components b0=2 and the number of windows b1=4 and the ratio b1/b0=4/2=1.5.Back to article page
