- W2356908413 abstract "Study key images extraction in video images.In traditional video image technology,key frames are based on the key characteristics of images.When the key image characteristics are not obvious or repetitive with non-critical image features,the method based on feature extraction may have errors,and the error rate and miss rate are high.The paper proposed a RS theory based key frame extraction method.Firstly,the algorithm extracted image DCT coefficient,used the attribute reduction of the RS theory to produce the kernel of information system,which was the key frames when corresponded to videos.The method can avoid depending key features as the traditional method does.Experimental results show that the algorithm and improve the accuracy of key frame extraction and achieve good effect." @default.
