Original data

ISCT method
|
Nearest Neighbor
|
B-spline
|
|
Spatial interpolation technology for video and still images enlarges the received small images with better image quality.
For example, this technology changes the received QVGA image into VGA size.
For 200% enlargement the necessary data are only 1/4, since the enlargement is done two times both for vertical and horizontal directions.

Temporal
Interpolation
|
|
Depending upon the moving speed of objects in the video, this technology converts (interpolates) 7.5 fps image into, for example, 15 fps image, or 10 fps image into, for example, 30 fps image. By the interpolation the object movement in video becomes very smooth.

Detection
function
|
- Object identification and detection : this function specifies the form of objects and identifies men, animals and objects.
- Automatic pursuit of objects : pursuit of selected moving objects in the video stream
- Object color recognition : Recognition of color for the selected object and storing its information
|
This technology makes it possible to specify the moving men or objects and also the colors of their cloths or their moving locations. This information is inserted in the image data obtained by monitor camera. This enables the quick search of necessary information from the big volume of data.
