16.07 - An N-Point Statistics Framework for Predicting Tissue Traits in Biomedical Images

Project - Summary


To develop a general biomedical image informatics framework that is capable of predicting the traits of tissues captured in images of immunohistochemistry-stained (IHC) specimens. Our work on the framework has been on-going for a number of years. The CVDI Year 5 funding supported three separate sub-projects that contributed to the enhancement of the framework. They are:

  • Definition of an alternate color representation for the analysis of Hematoxylin and Eosin (H&E) images (a type of IHC image), which supports color normalization that effectively reduces inter-slide variability during downstream analysis.
  • Estimation of fine-scale histologic features at low magnification which allows for the analysis of IHC images at lower pixel resolutions; thus providing computational speed-ups that facilitate high-throughput analysis of while-slide IHC images.
  • Development of an approach for characterization spatial structures in biomedical images based on N-point statistics analysis. The features derived from the analysis may be used to predict tissue traits.

Project - Impact and Uses/Benefits

We envision multiple impacts and uses for the technologies developed in the three sub-projects. They are:

  • SP1: Providing an improved tissue structure segmentation algorithms based on our alternative color space for H&E images.
  • SP1: Supporting color normalizataion that will alleviate the problem of staining variability, a major impediment to automated processing and anaylsis of H&E images.
  • SP2: The ability to estimate the histological composition of tissue in low-resolution images will facilitate the computational analysis of whole-slide images; thus enabling automated and high-throughput tissue analysis in pathology.
  • SP3: N-point statistics provides a method for characterizing the architecture of tumors; thus improving the automated analysis/grading of tissues that should lead to improved, more accurate and robust diagnosis of cancer.
