A system comprising: a bleeding detection unit configured to couple to an image capture system and a display unit, the image capture system being configured to acquire a frame of data of a scene of a surgical site, wherein the frame includes a plurality of locations, and wherein each location of the plurality of locations includes pixels for a plurality of color components; wherein the bleeding detection unit comprises: a region segmentation module configured to: receive the frame of data; detect whether the plurality of color component pixels of each location of the plurality of locations includes information indicative of blood at that location; and determine a region of blood in the scene based on locations of the plurality of locations detected as including information indicative of blood; a region of blood identification module coupled to the region segmentation module and configured to: determine whether the region of blood in the scene is an initial region of blood in the scene; generate an initial site icon to indicate an initial region of blood in the scene, when the region of blood in the scene is the initial region of blood in the scene; and combine the initial site icon with the scene to generate data including a combined scene; and wherein the bleeding detection unit is configured to send, to the display unit, the data including the combined scene for display, by the display unit, of the combined scene; wherein the region of blood identification module is further configured to combine the initial site icon with a respective scene of each of a plurality of subsequent frames of data to generate data including a combined scene for each of the subsequent frames; and wherein the bleeding detection unit is further configured to send, to the display unit, the data including the combined scene for each of the subsequent frames for display, by the display unit, of the combined scene for each of the subsequent frames, thereby indicating the initial region of blood in the combined scene for each of the subsequent frames. a bleeding detection unit configured to couple to an image capture system and a display unit, the image capture system being configured to acquire a frame of data of a scene of a surgical site, wherein the frame includes a plurality of locations, and wherein each location of the plurality of locations includes pixels for a plurality of color components;
