Pedestrian detection has achieved significant progress with the availability of existing
benchmark datasets. However, there is a gap in the diversity and density between real world …

Perceptual hashing is used for multimedia content identification and authentication through
perception digests based on the understanding of multimedia content. This paper presents a …

Image hash functions find extensive applications in content authentication, database search,
and watermarking. This paper develops a novel algorithm for generating an image hash …

We propose an image hashing paradigm using visually significant feature points. The
feature points should be largely invariant under perceptually insignificant distortions. To …

Due to the ever increasing digitalization, the authentication of multimedia content is
becoming more and more important. Authentication in general means deciding whether an …

In this paper we suggest viewing images (as well as attacks on them) as a sequence of
linear operators and propose novel hashing algorithms employing transforms that are based …

In this paper, we propose the use of non-negative matrix factorization (NMF) for image
hashing. In particular, we view images as matrices and the goal of hashing as a randomized …

感知哈希(Perceptual Hashing), 是多媒体数据集到感知摘要集的一类单向映射,
即将具有相同感知内容的多媒体数字表示唯一地映射为一段数字摘要, 并满足感知鲁棒性和安全 …

Identification and verification of a video clip via its fingerprint find applications in video
browsing, database search and security. For this purpose, the video sequence must be …

Perceptual image hash has been widely investigated in an attempt to solve the problems of
image content authentication and content-based image retrieval. In this paper, we combine …
