Image authentication using LBP-based perceptual image hashing
Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...
متن کاملRobust Image Content Authentication Using Perceptual Hashing and Watermarking
Perceptual hashing is a promising tool for multimedia content authentication. Digital watermarking is a convenient way of data hiding. By combining the two, we get a more efficient and versatile solution. In a typical scenario, multimedia data is sent from a server to a client. The corresponding hash value is embedded in the data. The data might undergo incidental distortion and malicious modif...
متن کاملA Novel Method for Content Base Image Retrieval Using Combination of Local and Global Features
Content-based image retrieval (CBIR) has been an active research topic in the last decade. In this paper we proposed an image retrieval method using global and local features. Firstly, for local features extraction, SURF algorithm produces a set of interest points for each image and a set of 64-dimensional descriptors for each interest points and then to use Bag of Visual Words model, a cluster...

متن کاملRobust image hashing using ring partition-PGNMF and local features
BACKGROUND Image authentication is one of the challenging research areas in the multimedia technology due to the availability of image editing tools. Image hash may be used for image authentication which should be invariant to perceptually similar image and sensitive to content changes. The challenging issue in image hashing is to design a system which simultaneously provides rotation robustnes...
