GCTI-SN is a Geometry-inspired Chemical-invariant and Tissue Invariant Stain Normalization method. The proposed GCTI-SN method corrects for illumination variation, stain chemical, and stain quantity variation in a unified framework by exploiting the underlying color vector space’s geometry. While existing stain normalization methods have demonstrated their results on a single tissue and stain type, GCTI-SN is benchmarked on three cancer datasets of three cell/tissue types prepared with two different stain chemicals. the utility and the efficacy of the GCTI-SN stain normalization method is demonstrated diagnostically in the application of breast cancer detection via a CNN-based classifier. The dataset used is publicly available at [TCIA]. The article is available [here], and the code is available [here]. The BibTeX citation of the article is as follows:
