Computer Infrastructure

General Overview

High-performance computing infrastructure is required due to the huge sizes of whole-slide histopathology images and the sophisticated image analysis routines. We are working to develop efficient and effective computational processing methods for image analysis.

Current Findings:



GPUs

GPU stands for Graphics Processing Unit. Initially designed for gaming applications to implement complex rendering operations for real-time effects.





Now, with their improved performance they are being used for a variety of purposes.





Graph

We are using GPUs to process high-resolution histopathology images. We implemented the image analysis routines on GPU to classify stromal development for NB image analysis. GPU provided remarkable computational savings with 45 times faster processing. Processing of a relatively small whole-slide image with a resolution of 50Kx50K reduced to 47 sec. on GPU compared to 35 min. on CPU.
