Video transcoding is one of the key technologies in implementing dynamic bit rate adaptation of a pre-encoded video stream to the available bandwidth over various networks. Though there have been many different transcoding schemes, since they do not

IN this paper, we propose a new scene change detection (SCD) algorithm, and also provide a novel video-indexing scheme for fast content-based browsing and retrieval in video databases. We detect scene changes from the MPEG video sequence, and extract

This paper presents a new method of 3D surface feature extraction using not conventional surface normal vectors and curvatures but center, corner and subsidiary points. We assume that each region of object have a uniform surface curvature distributio

The IR seeker is a device that detects heats radiated from a target and provides the target position with servo system of the missile. Among various kinds of seekers, the rosette- scanning seeker ins a tracker in which a single IR detector scans the

A rosette scanning IR seeker is the device mounted on the IR guided missile. It offers the positions and images of target to missiles' servo system by scanning a total field of view (TFOV) in a rosette pattern with a single detector. An instantaneous

This paper presents a dynamic simulation loop that gives tracking results of 2-color concentric annular ring (CAR) reticle seeker. Our simulation tool includes the target/flare model and a proportional navigation guidance loop. The CAR reticle system

Reticle systems, which are widely used in infrared (IR) missile seekers, are considered to be the classical approach for estimating the position of a target in the field of view (FOV). This paper presents a new simulation tool that gives tracking res

A dynamic simulator of the reticle seekers has been developed to predict the tracking performance in various engagement scenarios. We can analyze the performance of the infrared (IR) reticle seekers with various positions of targets in the field of v

Reticle seekers temporally modulate target location onto the incoming spatial signal. When large or multiple targets are present in the FOV, however, it is hard to precisely modulate the incoming target signal by the reticle. To solve this loss of mo

For generation and analysis of the multi-sensory image, we propose a new three dimensional (3D) modeling method considering the internal heat source. We represent the heat transfer process within the object as the equivalent thermal circuit. Therefor
