Frustratingly Simple but Effective Zero-shot Detection and Segmentation: Analysis and a Strong Baseline

no code implementations14 Feb 2023 Siddhesh Khandelwal, Anirudth Nambirajan, Behjat Siddiquie, Jayan Eledath, Leonid Sigal

Methods for object detection and segmentation often require abundant instance-level annotations for training, which are time-consuming and expensive to collect.

Iterative Scene Graph Generation

no code implementations27 Jul 2022 Siddhesh Khandelwal, Leonid Sigal

In this work, we propose a novel framework for scene graph generation that addresses this limitation, as well as introduces dynamic conditioning on the image, using message passing in a Markov Random Field.

Segmentation-grounded Scene Graph Generation

no code implementations ICCV 2021 Siddhesh Khandelwal, Mohammed Suhail, Leonid Sigal

Our framework is agnostic to the underlying scene graph generation method and address the lack of segmentation annotations in target scene graph datasets (e. g., Visual Genome) through transfer and multi-task learning from, and with, an auxiliary dataset (e. g., MS COCO).

What-If Motion Prediction for Autonomous Driving

1 code implementation24 Aug 2020 Siddhesh Khandelwal, William Qi, Jagjeet Singh, Andrew Hartnett, Deva Ramanan

Forecasting the long-term future motion of road actors is a core challenge to the deployment of safe autonomous vehicles (AVs).

UniT: Unified Knowledge Transfer for Any-shot Object Detection and Segmentation

no code implementations CVPR 2021 Siddhesh Khandelwal, Raghav Goyal, Leonid Sigal

Weakly-supervised approaches draw on image-level labels to build detectors/segmentors, while zero/few-shot methods assume abundant instance-level data for a set of base classes, and none to a few examples for novel classes.

AttentionRNN: A Structured Spatial Attention Mechanism

no code implementations ICCV 2019 Siddhesh Khandelwal, Leonid Sigal

Visual attention mechanisms have proven to be integrally important constituent components of many modern deep neural architectures.
