Perceptual image hashing methods utilize the visual phenomenon of the images and
produce a fixed-length hash function and this hash value can be utilized for digital signature …

Perceptual hashing is a promising solution to image content authentication. However,
conventional image hash algorithms only offer a limited authentication level for the …

Perceptual image hashing technique uses the appearance of the digital media object as
human eye and generates a fixed size hash value. This hash value works as digital …

Video object tracking represents a very important computer vision domain. In this paper, a
perceptual hashing based template-matching method for object tracking is proposed to …

LSH is a popular framework to generate compact representations of multimedia data, which
can be used for content based search. However, the performance of LSH is limited by its …

In this paper, perceptual hash codes are adopted as appearance models of objects for
visual tracking. Based on three existing basic perceptual hashing techniques, we propose …

User authentication is essential for maintaining the security, privacy, and integrity of systems
and data. It ensures that only authorized individuals can access specific resources …

A hash algorithm converts data into compact strings. In the multimedia domain, effective
hashing is the key to large-scale similarity search in high-dimensional feature space. A limit …

This paper proposes an improvement method using image normalization for Radon
transform (RT)-based perceptual image hashing in which a normalized image is generated …

In this paper we describe a method for specific document sign location detection based on
key point grouping correspondence. The proposed method extracts stable points …
