GraPLUS: Graph-based Placement Using Semantics for Image Composition
Mir Mohammad Khaleghi, Mehran Safayani, Abdolreza Mirzaei
We present GraPLUS (Graph-based Placement Using Semantics), a novel framework for plausible object placement in images that leverages scene graphs and large language models. Our ap…
A Latent Variable Model for Two-Dimensional Canonical Correlation Analysis and its Variational Inference
Mehran Safayani, Saeid Momenzadeh
Describing the dimension reduction (DR) techniques by means of probabilistic models has recently been given special attention. Probabilistic models, in addition to a better interpr…
An EM Based Probabilistic Two-Dimensional CCA with Application to Face Recognition
Mehran Safayani, Seyed Hashem Ahmadi, Homayun Afrabandpey +1
Recently, two-dimensional canonical correlation analysis (2DCCA) has been successfully applied for image feature extraction. The method instead of concatenating the columns of the…
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…
Facial Expression Representation and Recognition Using 2DHLDA, Gabor Wavelets, and Ensemble Learning
Mahmoud Khademi, Mohammad H. Kiapour, Mehran Safayani +2
In this paper, a novel method for representation and recognition of the facial expressions in two-dimensional image sequences is presented. We apply a variation of two-dimensional…
