Wavelet-Based Image Registration With JPEG2000 Compressed Imagery

摘要

This paper describes a registration algorithm for aligning large frame imagery compressed with the JPEG2000 compression standard. The images are registered in the compressed domain using wavelet-based techniques. Unlike traditional approaches, our proposed method eliminates the need to reconstruct the full image prior to performing registration. The proposed method is highly scalable allowing registration to be performed on selectable resolution levels, quality layers, and regions of interest. The use of the hierarchical nature of the wavelet transform also allows for the trade-off between registration accuracy and processing speed. We present the results from our simulations to demonstrate the feasibility of the proposed technique in real-world scenarios with streaming sources. The wavelet-based approach maintains compatibility with JPEG2000 and enables additional features not offered by traditional approaches.
