A person counting device generates a single panorama image by using a plurality of images respectively captured by a plurality of cameras, inserts an imaginary line to the single panorama image; and counts the number of persons that pass the imaginary line. To this end, identification numbers are allocated to respective persons in the plurality of images, the single panorama image including the imaginary line is restored to a plurality of images including same imaginary line information, the number of persons that pass a new imaginary line in each of the plurality of restored images is determined, and the number of duplicate-counted persons is ruled out.

Method and apparatus for counting number of person using plurality of cameras

A method and system for detecting motion are provided. The method includes: generating a time domain matrix including vectors corresponding to variation of pixel values as elements of the time domain matrix, of a video image including a plurality of frames; generating a motion matrix from which a low frequency area of the video image is removed by multiplying the time domain matrix by a low rank matrix; and generating a result image including a plurality of frames in which vectors, which are elements of the motion matrix, are included as variation of motion pixel values.

Method and system for detecting matrix-based motion including frequency transform and filtering
