Audio-Visual Face Reenactment

1 code implementation6 Oct 2022 Madhav Agarwal, Rudrabha Mukhopadhyay, Vinay Namboodiri, C V Jawahar

The identity-aware generator takes the source image and the warped motion features as input to generate a high-quality output with fine-grained details.

FaceOff: A Video-to-Video Face Swapping System

no code implementations21 Aug 2022 Aditya Agarwal, Bipasha Sen, Rudrabha Mukhopadhyay, Vinay Namboodiri, C. V. Jawahar

To tackle this challenge, we introduce video-to-video (V2V) face-swapping, a novel task of face-swapping that can preserve (1) the identity and expressions of the source (actor) face video and (2) the background and pose of the target (double) video.

Towards MOOCs for Lipreading: Using Synthetic Talking Heads to Train Humans in Lipreading at Scale

no code implementations21 Aug 2022 Aditya Agarwal, Bipasha Sen, Rudrabha Mukhopadhyay, Vinay Namboodiri, C. V Jawahar

Because of the manual pipeline, such platforms are also limited in vocabulary, supported languages, accents, and speakers and have a high usage cost.

Personalized One-Shot Lipreading for an ALS Patient

no code implementations2 Nov 2021 Bipasha Sen, Aditya Agarwal, Rudrabha Mukhopadhyay, Vinay Namboodiri, C V Jawahar

Apart from evaluating our approach on the ALS patient, we also extend it to people with hearing impairment relying extensively on lip movements to communicate.

Towards Automatic Speech to Sign Language Generation

1 code implementation24 Jun 2021 Parul Kapoor, Rudrabha Mukhopadhyay, Sindhu B Hegde, Vinay Namboodiri, C V Jawahar

Since the current datasets are inadequate for generating sign language directly from speech, we collect and release the first Indian sign language dataset comprising speech-level annotations, text transcripts, and the corresponding sign-language videos.

Knowledge Consolidation based Class Incremental Online Learning with Limited Data

no code implementations12 Jun 2021 Mohammed Asad Karim, Vinay Kumar Verma, Pravendra Singh, Vinay Namboodiri, Piyush Rai

In our approach, we learn robust representations that are generalizable across tasks without suffering from the problems of catastrophic forgetting and overfitting to accommodate future classes with limited samples.

A Lip Sync Expert Is All You Need for Speech to Lip Generation In The Wild

3 code implementations23 Aug 2020 K R Prajwal, Rudrabha Mukhopadhyay, Vinay Namboodiri, C. V. Jawahar

However, they fail to accurately morph the lip movements of arbitrary identities in dynamic, unconstrained talking face videos, resulting in significant parts of the video being out-of-sync with the new audio.

Learning Individual Speaking Styles for Accurate Lip to Speech Synthesis

1 code implementation CVPR 2020 K R Prajwal, Rudrabha Mukhopadhyay, Vinay Namboodiri, C. V. Jawahar

In this work, we explore the task of lip to speech synthesis, i. e., learning to generate natural speech given only the lip movements of a speaker.

CovidAID: COVID-19 Detection Using Chest X-Ray

5 code implementations21 Apr 2020 Arpan Mangal, Surya Kalia, Harish Rajgopal, Krithika Rangarajan, Vinay Namboodiri, Subhashis Banerjee, Chetan Arora

This may be useful in an inpatient setting where the present systems are struggling to decide whether to keep the patient in the ward along with other patients or isolate them in COVID-19 areas.

Towards Automatic Face-to-Face Translation

1 code implementation ACM Multimedia, 2019 2019 Prajwal K R, Rudrabha Mukhopadhyay, Jerin Philip, Abhishek Jha, Vinay Namboodiri, C. V. Jawahar

As today's digital communication becomes increasingly visual, we argue that there is a need for systems that can automatically translate a video of a person speaking in language A into a target language B with realistic lip synchronization.

CPWC: Contextual Point Wise Convolution for Object Recognition

no code implementations21 Oct 2019 Pratik Mazumder, Pravendra Singh, Vinay Namboodiri

We propose an alternative design for pointwise convolution, which uses spatial information from the input efficiently.

Learning Semantic Sentence Embeddings using Sequential Pair-wise Discriminator

1 code implementation COLING 2018 Badri Narayana Patro, Vinod Kumar Kurmi, S. Kumar, eep, Vinay Namboodiri

One way to ensure this is by adding constraints for true paraphrase embeddings to be close and unrelated paraphrase candidate sentence embeddings to be far.

Multi-Agent Diverse Generative Adversarial Networks

1 code implementation CVPR 2018 Arnab Ghosh, Viveka Kulharia, Vinay Namboodiri, Philip H. S. Torr, Puneet K. Dokania

Second, to enforce that different generators capture diverse high probability modes, the discriminator of MAD-GAN is designed such that along with finding the real and fake samples, it is also required to identify the generator that generated the given fake sample.
