OCAI: Improving Optical Flow Estimation by Occlusion and Consistency Aware Interpolation

no code implementations26 Mar 2024 Jisoo Jeong, Hong Cai, Risheek Garrepalli, Jamie Menjay Lin, Munawar Hayat, Fatih Porikli

We propose OCAI, a method that supports robust frame interpolation by generating intermediate video frames alongside optical flows in between.

FutureDepth: Learning to Predict the Future Improves Video Depth Estimation

no code implementations19 Mar 2024 Rajeev Yasarla, Manish Kumar Singh, Hong Cai, Yunxiao Shi, Jisoo Jeong, Yinhao Zhu, Shizhong Han, Risheek Garrepalli, Fatih Porikli

In this paper, we propose a novel video depth estimation approach, FutureDepth, which enables the model to implicitly leverage multi-frame and motion cues to improve depth estimation by making it learn to predict the future at training.

DIFT: Dynamic Iterative Field Transforms for Memory Efficient Optical Flow

no code implementations9 Jun 2023 Risheek Garrepalli, Jisoo Jeong, Rajeswaran C Ravindran, Jamie Menjay Lin, Fatih Porikli

Also, we present a novel dynamic coarse-to-fine cost volume processing during various stages of refinement to avoid multiple levels of cost volumes.

DistractFlow: Improving Optical Flow Estimation via Realistic Distractions and Pseudo-Labeling

no code implementations CVPR 2023 Jisoo Jeong, Hong Cai, Risheek Garrepalli, Fatih Porikli

We propose a novel data augmentation approach, DistractFlow, for training optical flow estimation models by introducing realistic distractions to the input frames.

DejaVu: Conditional Regenerative Learning to Enhance Dense Prediction

no code implementations CVPR 2023 Shubhankar Borse, Debasmit Das, Hyojin Park, Hong Cai, Risheek Garrepalli, Fatih Porikli

Next, we use a conditional regenerator, which takes the redacted image and the dense predictions as inputs, and reconstructs the original image by filling in the missing structural information.

TransAdapt: A Transformative Framework for Online Test Time Adaptive Semantic Segmentation

no code implementations24 Feb 2023 Debasmit Das, Shubhankar Borse, Hyojin Park, Kambiz Azarian, Hong Cai, Risheek Garrepalli, Fatih Porikli

Test-time adaptive (TTA) semantic segmentation adapts a source pre-trained image semantic segmentation model to unlabeled batches of target domain test images, different from real-world, where samples arrive one-by-one in an online fashion.

Oracle Analysis of Representations for Deep Open Set Detection

no code implementations22 Sep 2022 Risheek Garrepalli

The second is to introduce Oracle representation learning, which produces a representation that is guaranteed to be sufficient for accurate anomaly detection.

Open Category Detection with PAC Guarantees

1 code implementation ICML 2018 Si Liu, Risheek Garrepalli, Thomas G. Dietterich, Alan Fern, Dan Hendrycks

Further, while there are algorithms for open category detection, there are few empirical results that directly report alien detection rates.
