X$^3$KD: Knowledge Distillation Across Modalities, Tasks and Stages for Multi-Camera 3D Object Detection

no code implementations3 Mar 2023 Marvin Klingner, Shubhankar Borse, Varun Ravi Kumar, Behnaz Rezaei, Venkatraman Narayanan, Senthil Yogamani, Fatih Porikli

Specifically, we propose cross-task distillation from an instance segmentation teacher (X-IS) in the PV feature extraction stage providing supervision without ambiguous error backpropagation through the view transformation.

Deep Markov Spatio-Temporal Factorization

1 code implementation22 Mar 2020 Amirreza Farnoosh, Behnaz Rezaei, Eli Zachary Sennesh, Zulqarnain Khan, Jennifer Dy, Ajay Satpute, J. Benjamin Hutchinson, Jan-Willem van de Meent, Sarah Ostadabbas

This results in a flexible family of hierarchical deep generative factor analysis models that can be extended to perform time series clustering or perform factor analysis in the presence of a control signal.

G-LBM:Generative Low-dimensional Background Model Estimation from Video Sequences

1 code implementation ECCV 2020 Behnaz Rezaei, Amirreza Farnoosh, Sarah Ostadabbas

Our model, called generative low-dimensional background model (G-LBM) admits variational operations on the distribution of the manifold coordinates and simultaneously generates a low-rank structure of the latent manifold given the data.

DeepPBM: Deep Probabilistic Background Model Estimation from Video Sequences

1 code implementation3 Feb 2019 Amirreza Farnoosh, Behnaz Rezaei, Sarah Ostadabbas

This paper presents a novel unsupervised probabilistic model estimation of visual background in video sequences using a variational autoencoder framework.

Background Subtraction via Fast Robust Matrix Completion

no code implementations3 Nov 2017 Behnaz Rezaei, Sarah Ostadabbas

In this regard, our paper addresses the problem of background modeling in a computationally efficient way, which is important for current eruption of "big data" processing coming from high resolution multi-channel videos.

Using Virtual Humans to Understand Real Ones

no code implementations13 Jun 2016 Katie Hoemann, Behnaz Rezaei, Stacy C. Marsella, Sarah Ostadabbas

Human interactions are characterized by explicit as well as implicit channels of communication.

Decoding Emotional Experience through Physiological Signal Processing

no code implementations1 Jun 2016 Maria S. Perez-Rosero, Behnaz Rezaei, Murat Akcakaya, Sarah Ostadabbas

Furthermore, in order to avoid information redundancy and the resultant over-fitting, a feature reduction method is proposed based on a correlation analysis to optimize the number of features required for training and validating each weak learner.
