Claim 2:
3. The device of claim 2, wherein one or more of the following:
(i) the object of the predetermined size is at least one of the following: a small object; and/or is an object corresponding to noise, residual blood, and/or other artifact(s);
(ii) the one or more processors further operate to delete any detected object of a predetermined size, and count how many objects are above a specific or predetermined distance from the imaging probe or count how many objects overlap with the BIA, where the specific or predetermined distance from the imaging probe is defined as an imaging probe distance, and the one or more processors further operate to compare the objects to the imaging probe distance value to decide whether the objects belong to blood or not;
(iii) the one or more processors further operate to delete any detected object of a predetermined size, and count how many objects are above a specific or predetermined distance from the imaging probe or count how many objects overlap with the BIA, and/or to define an imaging probe distance, the one or more processors further operate to measure an imaging depth at different blood state images or frames, and average the measurements; and/or
(iv) the specific or predetermined distance is defined by using images with blood presence.
