Perceptual hashing is an effective compression technology that maps the content of an image into a brief summary, which is essential for efficient processing in the Big Data era. However, most existing methods process images from a single view, leading to the omission of partial information. In addition, many methods utilize labels to construct a pairwise similarity matrix, which can result in significant time and space expenses. We propose a perceptual hashing algorithm based on collective matrix factorization. In particular, we embed the specific representations of each view and label information into a unified binary code learning framework. Specifically, a semantic label offset scheme is adopted to control the margins dynamically, which can avoid computational overhead, enhance semantic information, and improve the discrimination of the hashing. Experiments on several widely used datasets verify that when the threshold is |
