A Unified Transformer-based Network for multimodal Emotion Recognition

no code implementations27 Aug 2023 Kamran Ali, Charles E. Hughes

We then present our UBVMT network which is trained to perform emotion recognition by combining the 2D image-based representation of the ECG/PPG signal and the facial expression features.

Fine-grained Vibration Based Sensing Using a Smartphone

no code implementations8 Jul 2020 Kamran Ali, Alex X. Liu

VibroTag's accuracy is 37% higher than the average accuracy of 49. 25% achieved by one of the state-of-the-art IMUs based schemes, which we implemented for comparison with VibroTag.

Monitoring Browsing Behavior of Customers in Retail Stores via RFID Imaging

no code implementations7 Jul 2020 Kamran Ali, Alex X. Liu, Eugene Chai, Karthik Sundaresan

The key novelty of this paper is on achieving browsing behavior monitoring of multiple customers in front of display items by constructing coarse grained images via robust, analytical model-driven deep learning based, RFID imaging.

An Efficient Integration of Disentangled Attended Expression and Identity FeaturesFor Facial Expression Transfer andSynthesis

no code implementations1 May 2020 Kamran Ali, Charles. E. Hughes

In this paper, we present an Attention-based Identity Preserving Generative Adversarial Network (AIP-GAN) to overcome the identity leakage problem from a source image to a generated face image, an issue that is encountered in a cross-subject facial expression transfer and synthesis process.

All-In-One: Facial Expression Transfer, Editing and Recognition Using A Single Network

no code implementations16 Nov 2019 Kamran Ali, Charles. E. Hughes

In this paper, we present a unified architecture known as Transfer-Editing and Recognition Generative Adversarial Network (TER-GAN) which can be used: 1. to transfer facial expressions from one identity to another identity, known as Facial Expression Transfer (FET), 2. to transform the expression of a given image to a target expression, while preserving the identity of the image, known as Facial Expression Editing (FEE), and 3. to recognize the facial expression of a face image, known as Facial Expression Recognition (FER).

Facial Expression Recognition Using Human to Animated-Character Expression Translation

no code implementations12 Oct 2019 Kamran Ali, Ilkin Isler, Charles Hughes

In this paper we present a novel Human-to-Animation conditional Generative Adversarial Network (HA-GAN) to overcome these two problems by using many (human faces) to one (animated face) mapping.

Facial Expression Recognition Using Disentangled Adversarial Learning

no code implementations28 Sep 2019 Kamran Ali, Charles. E. Hughes

This expression representation is disentangled from identity component by explicitly providing the identity code to the decoder part of DE-GAN.
