    Abstract: A system for non-invasive hematological measurements includes a platform to receive a body portion of a user and an imaging device to acquire a set of images of a capillary bed in the body portion. For each image, a controller detects one or more capillaries in the body portion of the finger to identify a first set of capillaries by estimating one or more attributes of each capillary (e.g., structural attributes, flow attributes, imaging attributes, or combinations thereof), wherein at least one attribute of each capillary meets a predetermined criterion. The controller also identifies a second set of capillaries from the first set of capillaries such that each capillary of the second set of capillaries is visible in a predetermined number of images of the set of images.

    Abstract: According to certain general aspects, the present embodiments relate generally to identifying tissue, fluid and/or anatomical structures at the tip of a surgical tool. The determination of the tissue, fluid and/or anatomical structures that the tool is touching allows the inference of a position inside of a person undergoing surgery. For example, a surgeon may attempt to use a tool to interact with a lens portion of a person's eye during cataract surgery, but the identification of tissue provided by embodiments will indicate that the tool is at a position too deep inside of the eye.
