Figure 3.

The % accumulated variance for different number of eigenvectors (PC vectors). This plot has been generated using the spectral samples of nuclei, cytoplasm, red blood cells, fiber and white areas (areas which do not contain tissue). We can observe that with more number of PC vectors the variance of the data samples is captured better.
