SODAWideNet++: Combining Attention and Convolutions for Salient Object Detection

no code implementations29 Aug 2024 Rohit Venkata Sai Dulam, Chandra Kambhamettu

Additionally, the architecture of these backbones originally built for Image classification is sub-optimal for a dense prediction task like SOD.

Improving Normalization with the James-Stein Estimator

no code implementations1 Dec 2023 Seyedalireza Khoshsirat, Chandra Kambhamettu

In this paper, first, we establish that normalization layers in deep learning use inadmissible estimators for mean and variance.

SODAWideNet -- Salient Object Detection with an Attention augmented Wide Encoder Decoder network without ImageNet pre-training

1 code implementation8 Nov 2023 Rohit Venkata Sai Dulam, Chandra Kambhamettu

To achieve a shallower network, we increase the receptive field from the beginning of the network using a combination of dilated convolutions and self-attention.

Semantic Segmentation using Neural Ordinary Differential Equations

no code implementations18 Sep 2022 Seyedalireza Khoshsirat, Chandra Kambhamettu

The idea of neural Ordinary Differential Equations (ODE) is to approximate the derivative of a function (data model) instead of the function itself.

AIM: An Auto-Augmenter for Images and Meshes

no code implementations CVPR 2022 Vinit Veerendraveer Singh, Chandra Kambhamettu

Data augmentations are commonly used to increase the robustness of deep neural networks.

Learning Dense Stereo Matching for Digital Surface Models from Satellite Imagery

no code implementations8 Nov 2018 Wayne Treible, Scott Sorensen, Andrew D. Gilliam, Chandra Kambhamettu, Joseph L. Mundy

Digital Surface Model generation from satellite imagery is a difficult task that has been largely overlooked by the deep learning community.

Robust Shape Registration using Fuzzy Correspondences

no code implementations18 Feb 2017 Abhishek Kolagunda, Scott Sorensen, Philip Saponaro, Wayne Treible, Chandra Kambhamettu

We present a shape registration approach that solves for the transformation using fuzzy correspondences to maximize the overlap between the given shape and the target shape.

Localize Me Anywhere, Anytime: A Multi-Task Point-Retrieval Approach

no code implementations ICCV 2015 Guoyu Lu, Yan Yan, Li Ren, Jingkuan Song, Nicu Sebe, Chandra Kambhamettu

The main contribution of our paper is that we use a 3D model reconstructed by a short video as the query to realize 3D-to-3D localization under a multi-task point retrieval framework.

Material Classification With Thermal Imagery

no code implementations CVPR 2015 Philip Saponaro, Scott Sorensen, Abhishek Kolagunda, Chandra Kambhamettu

Typical algorithms use color and texture information for classification, but there are problems due to varying lighting conditions and diversity of colors in a single material class.
