Measuring blood flow velocity from intravital video recordings

There is an obvious scientific interest in computing blood flow velocity from intravital microscopy using digital video cameras attached to microscopes. Therefore, software capable of measuring blood flow velocity from videos is of major importance. In this work, a novel software tool is presented. The software tackles three main issues in velocity measurement from videos, the registration, segmentation, and finally the measuring itself. The software was tested in chick chorioallantoic membrane (CAM) videos captured with different resolutions, frame rates, and even cameras. The obtained results show the robustness achieved.
