The method includes receiving a set of reference patch locations in a reference frame and reference patch alignment data for each location and receiving a frame of captured video. A first offset and a first subset of patch locations are selected from the set of reference patch locations. A second offset more than a pre-determined distance from the first offset and a second subset of patch locations from the reference patch locations are selected.

Abstract: An exemplary compounding method of controlling a compounding device to prepare an admixture of at least two distinct material sources can include examining material source solutions for incompatibility of the ingredients and operating a first and a second pump to prevent one of the incompatible source solutions from entering a common flow path. The processing method can detect degradation of a fluid line by evaluating one or more of calibration error rate data, cumulative volumetric flow data, or cumulative pump operation data. The processing method can also selectively transfer a first group of source solutions using the first pump, receiving pump data from one or more sensors that sense actions of the pumps, applying fluid correction factors and calculating discrete pump movements, the pump movements being indicative of an amount of source solution displacement by a pump, and operating the pumps to selectively dispense the source solution amounts according to a preparation order.
