Lower Limber Joints Location of Human Body in Gait Serial Images
Fu Liu · Jisuanji fangzhen · 2011
In computer vision research field,the lower limb joints of human body location are one of the important research topics in the domain of human motion tracking and analysis,and many methods have achieved encouraging effects.First,moving silhouettes were detected by a background subtraction from image sequences,then skeleton model of lower limbs and silhouette model of crura were built.The knee joint position and approximate ankle joint position were obtained automatically by circle intersection pointing algorithm based on motion modeling with frame continuity and crura silhouette data.Finally,exact position of ankle joints was captured through matching computing based on silhouette model of crura.The paper lists experimental results,and shows that this method has satisfying performance.
