PSFHS challenge report: Pubic symphysis and fetal head segmentation from intrapartum ultrasound images.

Segmentation of the fetal and maternal structures, particularly intrapartum ultrasound imaging as advocated by the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) for monitoring labor progression, is a crucial first step for quantitative diagnosis and clinical decision-making. This requires specialized analysis by obstetrics professionals, in a task that i) is highly time- and cost-consuming and ii) often yields inconsistent results. The utility of automatic segmentation algorithms for biometry has been proven, though existing results remain suboptimal.

Digital extractor: analysis of digital differential display output.

Digital Extractor is a program for the high-throughput processing of data sets derived from digital differential display-based comparisons of EST libraries. These comparisons can be utilized to identify discrete subsets of genes whose expression is restricted to distinct tissue types. The program facilitates these investigations by permitting parallel annotation of genes identified as being differentially expressed.
