With the increasing popularity of digital camera, organizing and managing the large collection of digital photos effectively become popular. Most researchers focus on clustering and image retrieval, but never on photo album compression. Some set redundancy methods for compressing similar image sets cannot handle photo album compression well because they don't account for any camera and object motion information between images. In this paper, we analyzed the characteristics of camera and object motion between similar photos and designed a novel lossy coding scheme for similar image sets. In our proposed coding scheme, we applied Global Motion Compensation (GMC), Local Motion Compensation (LMC) and Intra prediction inspired from video coding technology. Our method provides a compact and reasonable format for people to store and transmit their large number of digital photos. Experiments prove that our algorithm is efficient and effective for digital photo processing.
