Differences between automated segmentations and ground truth caused by membranes parallel to the focal planes. (Left to right) Original image, BCOMS, ground truth, and pixel-level difference in the 24-cell stage embryo. 3D view images (a) and 2D view images (b, Z=22; c, Z=35). The cellular regions in the BCOMS segmentations and the ground truth are represented by different colors. For each pixel in each cell of the automated segmentation result, the pixel level difference was measured as the distance from the nearest pixel in the corresponding cell of the ground truth, and is displayed in pseudo color. The differences increase at the contacting surfaces of adjacent cells (b), and at bare surfaces that do not contact with other cells (c)
