Workflow: (a) The hyperspectral (HS) images from the mosaic 5 × 5 hyperspectral camera were acquired after cytoreduction. (b) HS images were pre-processed by calibration, min-max normalization and noise filtering and transformed. (c) The digitized pathological images were annotated. (d) The annotated images were transformed. Tumor tissue was filled with the color bordeaux and the non-tumor tissue was filled with the color blue. (e) Tumor tissue and non-tumor tissue were selected via hue, saturation and value (HSV) color thresholding to make masks. (f) Selection of the tumor tissue and non-tumor tissue was made with the mask. (g) The HS images were multiplied by the mask to obtain tumor tissue and non-tumor tissue. (h) The HS images were patched into a grid of 20 × 20 pixels and features were extracted.
