Lung transplantation is an advanced treatment available for end-stage respiratory illnesses. Unfortunately, a portion of the donor pool is rejected due to uncertainty about the lung's state of health. Ex Vivo Lung Perfusion (EVLP) is a preservation technique that monitors donor lung performance at a near-physiological state. Performance metrics obtained from the EVLP system are used to evaluate donor lung transplant viability. A computer stereo vison method is proposed to measure
