Mehran Safayani, Amir Sartipi, Amir Hossein Ahmadi +4
The proliferation of hate speech and offensive comments on social media has become increasingly prevalent due to user activities. Such comments can have detrimental effects on indi…
Clustering based on Mixtures of Sparse Gaussian Processes
Zahra Moslehi, Abdolreza Mirzaei, Mehran Safayani
Creating low dimensional representations of a high dimensional data set is an important component in many machine learning applications. How to cluster data using their low dimensi…
Duplicate matching and estimating features for detection of copy-move images forgery
Ghassem Alikhajeh, Abdolreza Mirzaei, Mehran Safayani +1
Copy-move forgery is the most popular and simplest image manipulation method. In this type of forgery, an area from the image copied, then after post processing such as rotation an…
Extended Two-Dimensional PCA for Efficient Face Representation and Recognition
Mehran Safayani, Mohammad T. Manzuri-Shalmani, Mahmoud Khademi
In this paper a novel method called Extended Two-Dimensional PCA (E2DPCA) is proposed which is an extension to the original 2DPCA. We state that the covariance matrix of 2DPCA is e…
Multilinear Biased Discriminant Analysis: A Novel Method for Facial Action Unit Representation
Mahmoud Khademi, Mehran Safayani, Mohammad T. Manzuri-Shalmani
In this paper a novel efficient method for representation of facial action units by encoding an image sequence as a fourth-order tensor is presented. The multilinear tensor-based e…
