A method for automatic segmentation of tumour regions in breast histopathology images is described. It uses auto-context to label pixels based on local image features and contextual label probabilities. We propose spin-context to compute context features that are invariant under image rotation. Quantitative evaluation is reported using spots stained for estrogen receptor. The use of context resulted in improved segmentation.
