1. A method for estimating extracorporeal blood volume in at least a portion of a physical sample, the method comprising:
associating a physical dimension of the portion of the physical sample with an image of the physical sample captured by an optical sensor by determining at least one of an estimated distance and an estimated angle between a capture origin of the image and the portion of the physical sample based on a returned signal transmitted from a distance sensor towards the physical sample;
extracting a feature from the image of the physical sample;
estimating the extracorporeal blood volume in the portion of the physical sample based on the extracted feature and the determined at least one of the estimated distance and the estimated angle; and
displaying on a display the estimated extracorporeal blood volume.
