Detection of pan and zoom in soccer sequences based on H.264/AVC motion information

Unsupervised detection of pan and zoom in soccer sequences allows automatic classification of shots and match analysis. In this work we propose a pan and zoom (both in and out) detector specifically designed for low resolution soccer sequences. Our implementation is based on the analysis of the distribution of the motion vectors, already available in the encoded sequence, among a specific subset of reliable MBs, selected by means of inexpensive image preprocessing.
