| Description | Interface of virtual microscope forms a part of the hypertext atlas of Dermatopathology, the Atlas of Fetal and Neonatal Pathology and the hypertext atlas of Pathology (http://www.muni.cz/atlases). These atlases offer number of clinical macroscopic and microscopic images together with short introductory texts. Images are obtained in high resolution using automated microscope and image stitching, possibly in more focusing planes. Each histological image is formed by a matrix of tiles, each tile is a file of 2500x1900 pixels. One histological image encompasses about 30,000 tiles. Histological images processing is not only computation intensive but requires high disk and network bandwidth either. Moreover, some operations require huge amount of system memory. Image processing is not optimal to run on a single workstation (even well dimensioned). We can utilize distributed computational infrastructure so that parts of image processing are run in parallel on many lightweight computer nodes. Our preliminary experiments in distributed environment show good time improvement of image processing. We also verified that utilization of distributed environment is feasible. More work needs to be done to transform whole image processing workflow into distributed environment. |
