Twi-difference Algorithm and Pixel-matching Twi-difference Algorithm for Video Abrupt Shot Change Detection
The shot change detection is a basic and important technology in video retrieval. There are some basic algorithms
including the template matching algorithm
the histogram algorithm
etc.
used to detect abrupt shot change in digital video
but they can't always attain high precision in practical detecting. A new algorithm used to eliminate the influence of the video movement on the shot change detection
named twi difference algorithm
and a new algorithm used to calculate the frame to frame difference of two images
called the pixel matching algorithm
are proposed in this paper. It is proved that the twi difference algorithms obviously improve the detecting precision in comparison with the direct frame to frame difference algorithms
and the pixel matching algorithm attains higher detecting precision than the basic frame to frame difference algorithms in being
and the pixel matching twi difference algorithm
which can realize the no missing detection for the abrupt shot change on the condition of no or few false detection
