Digital image processing now can be economically applied to the motion analysis of objects taken by the high speed phtography. This paper will review some of common techniques. The identification of objects, motion detection and motion tracking are discussed. These procedures are neither independent nor in sequence. Forward and backward feedbacks of knowledges accumulated during processing are important in order to reduce the processing time and increase the reliability.
