Fig. 4From: Biologically constrained optimization based cell membrane segmentation in C. elegans embryosAccurate segmentations across focal planes and time pointsShown are the membrane images and segmentation results computed by BCOMS at representative developmental stages and focal (Z) planes. The bottom and top focal planes are denoted as ZÂ =Â 1 and ZÂ =Â 36, respectively. The top panels are the 3D volume renderings of the membrane images and segmentation results. Cellular regions are rendered in different colors and the segmented membranes and background are rendered in blackBack to article page
