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

gains the best detecting precision.
