BMPER regulates cardiomyocyte size and vessel density in vivo [PDF]

Cardiovascular Pathology, 2013
BMPER, an orthologue of Drosophila melanogaster Crossveinless-2, is a secreted factor that regulates bone morphogenetic protein activity in endothelial cell precursors and during early cardiomyocyte differentiation. Although previously described in the heart, the role of BMPER in cardiac development and function remain unknown.

Retinal vessel segmentation using the 2-D Gabor wavelet and supervised classification [PDF]

, 2006
—We present a method for automated segmentation of the vasculature in retinal images. The method produces segmentations by classifying each image pixel as vessel or nonvessel, based on the pixel’s feature vector. Feature vectors are composed of the pixel’
