Video data is increasingly being used in medical diagnosis. Due to the quality of the video and the complexities of underlying motion captured, it is difficult for an in-experienced physician/radiologist to describe motion abnormalities in a crisp way, leading to possible errors in diagnosis. In this paper, we present a method of capturing video similarity and its use for diagnosis verification during decision support. Specifically, we describe the motion information in videos using average velocity curves. Second-order motion statistics are extracted from average velocity curves and serve as features for computing video similarity. Given a new video sample already labeled with a diagnosis, a neighborhood of similar videos is assembled from the training set and their diagnosis labels are used to verify the diagnosis.
