Markerless camera-based games are more immersive and compelling than other types of games. However, it is difficult to select the proper methods for body segmentation and motion detection, because they should be fast processed for real-time responses. Therefore, collision detection and response between virtual objects (VOs) and human bodies are estimated using collision regions. In this paper, we...
This paper proposes a new approach to detect exceptional motion frames from real videos irrespective of both static and dynamic backgrounds. The approach is based on the use of the spatiotemporal region of interest (ST-RoI) features obtained from ST-RoI, which is estimated using motion history image (MHI). Within ST-RoI, exceptional motion makes the motion vectors (e.g., directions) change a lot as...
We present a simple and lightweight approach to scene analysis in the H.264/SVC domain. The method is entirely based on the motion vectors found in the compressed stream. Motion segmentation and object detection is performed after the estimation of the camera motion. Important object properties are calculated, which are used for object matching and trajectory estimation. The relative distance to the...
Detecting pedestrians using conventional optical camera has got many problems. Itpsilas difficult to be used to detect pedestrian using only single optical camera. Detecting pedestrians in a crowded environment from other objects is a very difficult task. This paper presents a method to detect multiple pedestrians from a moving camera. The detection component involves a cascade of modules. We used...
