Automatic Framework for Processing Drosophila Embryonic Images (NSF IIS)

Project Summary:

High resolution embryonic images, e.g., the data set BDGP (Berkley Drosophila Genome Project), have been introduced as an important tool for the discovery of gene-gene interaction. These images contain not only temporal information of a gene but also precise spatial information of expression regions of genes. So the biologic problem of the discovery of gene-gene interaction can be characterized as a computational problem of matching expression patterns of embryos at the same developmental stage. It is, however, very challenging to design a fully automatic computational system due to severe imaging and artificial variations in embryonic images. Current research on embryonic image processing involves significant manual manipulation or addresses only a small subset of variations. In this project, I will develop a comprehensive automatic framework to achieve the three fundamental tasks: image standardization, stage determination, and expression pattern modeling.
