Image-Based Synchronization in Mobile TV for a Multi-Broadcast-Receiver
نویسندگان
چکیده
In this paper we propose a novel technique for imagebased synchronization of two mobile received TV sequences having different spatial resolutions, deviant image qualities, and possibly lost image blocks. The sequences are aligned spatially and temporally based on an affine transform. The optimal transformation parameters are determined numerically by the LevenbergMarquardt-Algorithm due to complexity reasons. The presented algorithm leads to accurate synchronization of mobile TV and is robust even in case of image cropping and arbitrarily shaped error patterns.
