This paper proposes a Two Minimum Three Step Search (2MN3SS) block matching algorithm that improves the estimation accuracy and retains the simplicity of the Three Step Search (3SS) algorithm. Motion estimation using Full Search (FS) algorithm is computationally extensive. Other previously proposed algorithms reduce the computation by limiting the number of search points at the cost of higher distortion...
The paper deals with the issue of intrusion detection in video surveillance using the time-of-flight (ToF) camera, exploiting the special ability of the device to measure distances. Two different detection methods (based on histogram and motion estimation) are presented and compared. Finally, a simple tracking algorithm is proposed and extended to automatically track of multiple moving persons.
Motion detection is a very important function in an intelligent video surveillance system. In order to detect the moving objects, it is necessary to generate the correct background image for each frame of the surveillance video. By subtracting the correct background image from the original image, the motion objects are derived in each frame of the surveillance video. Based on removing the motion objects...
