Sequential Ensembling for Semantic Segmentation

no code implementations8 Oct 2022 Rawal Khirodkar, Brandon Smith, Siddhartha Chandra, Amit Agrawal, Antonio Criminisi

Ensemble approaches for deep-learning-based semantic segmentation remain insufficiently explored despite the proliferation of competitive benchmarks and downstream applications.

Multi-Instance Pose Networks: Rethinking Top-Down Pose Estimation

1 code implementation ICCV 2021 Rawal Khirodkar, Visesh Chari, Amit Agrawal, Ambrish Tyagi

Specifically, we achieve 70. 0 AP on CrowdPose and 42. 5 AP on OCHuman test sets, a significant improvement of 2. 4 AP and 6. 5 AP over the prior art, respectively.

PoseNet3D: Learning Temporally Consistent 3D Human Pose via Knowledge Distillation

1 code implementation7 Mar 2020 Shashank Tripathi, Siddhant Ranade, Ambrish Tyagi, Amit Agrawal

Finally, both the teacher and the student networks are jointly fine-tuned in an end-to-end manner using temporal, self-consistency and adversarial losses, improving the accuracy of each individual network.

Learning to Generate Synthetic Data via Compositing

no code implementations CVPR 2019 Shashank Tripathi, Siddhartha Chandra, Amit Agrawal, Ambrish Tyagi, James M. Rehg, Visesh Chari

The synthesizer and target networks are trained in an adversarial manner wherein each network is updated with a goal to outdo the other.

"When and Where?": Behavior Dominant Location Forecasting with Micro-blog Streams

no code implementations16 Dec 2018 Bhaskar Gautam, Annappa Basava, Abhishek Singh, Amit Agrawal

The proliferation of smartphones and wearable devices has increased the availability of large amounts of geospatial streams to provide significant automated discovery of knowledge in pervasive environments, but most prominent information related to altering interests have not yet adequately capitalized.

CRAFT: Complementary Recommendations Using Adversarial Feature Transformer

no code implementations29 Apr 2018 Cong Phuoc Huynh, Arridhana Ciptadi, Ambrish Tyagi, Amit Agrawal

Such a conditional generative model can produce multiple novel samples of complementary items (in the feature space) for a given query item.

Context Encoding for Semantic Segmentation

12 code implementations CVPR 2018 Hang Zhang, Kristin Dana, Jianping Shi, Zhongyue Zhang, Xiaogang Wang, Ambrish Tyagi, Amit Agrawal

In this paper, we explore the impact of global contextual information in semantic segmentation by introducing the Context Encoding Module, which captures the semantic context of scenes and selectively highlights class-dependent featuremaps.

Single Image Calibration of Multi-axial Imaging Systems

no code implementations CVPR 2013 Amit Agrawal, Srikumar Ramalingam

We describe such setups as multi-axial imaging systems, since a single sphere results in an axial system.
