Abstract:
In the past three years, we have collaborated with the Univ. of Colorado, Boulder, USA, and the Institute for Medical Pathology at the Medical University, Vienna. The focus of our research was on developing image analysis systems using state-of-the-art techniques, including machine learning techniques which have been previously used to recognize faces. We have developed robust preprocessing methods (stitching, illumination correction, erythrocyte removal), segmentation algorithms and task-specific evaluation algorithms based on ground-truth data provided by our biological researcher partners. We have analyzed three different types of tissue: human osteoclast in culture, human placental tissue, and living transgenic C. elegans specimen.
We will close with thoughts on the potential uses of image data analysis, what is and is not yet feasible, and how biological researchers should be expected to help in the building of state-of-the-art systems.
