VIDEO SYNCHRONIZATION TECHNIQUES USING PROJECTION

摘要

Examples of video synchronization techniques are described. Example synchronization techniques may utilize projection on convex spaces (POCS). The use of POCS may reduce complexity and may speed up synchronization in some examples. Projection on convex spaces generally involves projection (e.g. through summation, averaging, and/or quantization) of samples corresponding to a certain domain or dimension onto a particular axis or space. Weighted projection (e.g. averaging and/or summation) may also be used.

1. A method for synchronizing a target and reference video clip, the method comprising:
projecting samples of the reference clip from at least one dimension onto a particular space to provide at least one search vector representative of the reference clip; projecting samples of the target clip from the at least one dimension onto the particular space to provide at least one search vector representative of the target clip; and comparing the at least one search vector representative of the reference clip and the at least one search vector representative of the target clip to select a synchronization point.
