A Revision Control System for Image Editing in Collaborative Multimedia Design
This addresses storage and semantic issues for multimedia designers, but it is incremental as it builds on existing revision control concepts.
The paper tackles the lack of revision control for binary files like images in collaborative design by presenting a graph-based system integrated with Git, with a preliminary user study showing usability.
Revision control is a vital component in the collaborative development of artifacts such as software code and multimedia. While revision control has been widely deployed for text files, very few attempts to control the versioning of binary files can be found in the literature. This can be inconvenient for graphics applications that use a significant amount of binary data, such as images, videos, meshes, and animations. Existing strategies such as storing whole files for individual revisions or simple binary deltas, respectively consume significant storage and obscure semantic information. To overcome these limitations, in this paper we present a revision control system for digital images that stores revisions in form of graphs. Besides, being integrated with Git, our revision control system also facilitates artistic creation processes in common image editing and digital painting workflows. A preliminary user study demonstrates the usability of the proposed system.
