Digital pathology enables applications that are not possible using traditional microscopy and facilitates new ways of handling and presenting whole slide image data, along with quantitative evaluation. Differently stained tissue, highlighting specific biological functions, contains a vast amount of spatial information that must be interpreted by a pathologist. With automated image analysis, some of this information can be quantified and made available for computations such as stain expression analysis. In this contribution we present an automated workflow where quantitative image analysis results of consecutive, differently stained tissue sections are locally fused by co-registration. The results are spatially resolved feature vectors containing features like the densities of positively marked cell types for different stains, which are – in this sense – hyperspectral. Heat maps with many layers (hyperspectral) are generated from this data, revealing relationships between different stains that would not be evident from single stains alone. These hyperspectral data are also a starting point for further investigations; in supporting biomarker discovery in oncology, a systematic search for properties that correlate with clinical data for a patient cohort can be performed in an highly automated way.
