DEff-GAN: Diverse Attribute Transfer for Few-Shot Image Synthesis

1 code implementation28 Feb 2023 Rajiv Kumar, G. Sivakumar

While single image methods can synthesize image samples with diversity, they do not model multiple images or capture the inherent relationship possible between two images.

FPCD: An Open Aerial VHR Dataset for Farm Pond Change Detection

no code implementations28 Feb 2023 Chintan Tundia, Rajiv Kumar, Om Damani, G. Sivakumar

In this paper, we introduce a publicly available object detection and instance segmentation (OD/IS) dataset for localizing farm ponds from aerial imagery.

Deriving Surface Resistivity from Polarimetric SAR Data Using Dual-Input UNet

no code implementations5 Jul 2022 Bibin Wilson, Rajiv Kumar, Narayanarao Bhogapurapu, Anand Singh, Amit Sethi

DI-UNet uses a deep learning architecture to predict the resistivity using full polarimetric SAR data by promising a quick survey addition to the traditional method.

The MIS Check-Dam Dataset for Object Detection and Instance Segmentation Tasks

no code implementations30 Nov 2021 Chintan Tundia, Rajiv Kumar, Om Damani, G. Sivakumar

Deep learning has led to many recent advances in object detection and instance segmentation, among other computer vision tasks.

Learning Unsupervised Cross-domain Image-to-Image Translation Using a Shared Discriminator

1 code implementation9 Feb 2021 Rajiv Kumar, Rishabh Dabral, G. Sivakumar

We assess the qualitative and quantitative results on image transfiguration, a cross-domain translation task, in a setting where the target domain shares similar semantics to the source domain.

Symbolic powers of certain cover ideals of graphs

no code implementations1 Mar 2019 Arvind Kumar, Rajiv Kumar, Rajib Sarkar, S. Selvaraja

In this paper, we compute the regularity and Hilbert series of symbolic powers of the cover ideal of a graph $G$ when $G$ is either a crown graph or a complete multipartite graph.

Basis Pursuit Denoise with Nonsmooth Constraints

no code implementations28 Nov 2018 Robert Baraldi, Rajiv Kumar, Aleksandr Aravkin

These formulations are widely used, particularly for matrix completion and sparsity promotion in data interpolation and denoising.

Beating level-set methods for 3D seismic data interpolation: a primal-dual alternating approach

no code implementations9 Jul 2016 Rajiv Kumar, Oscar López, Damek Davis, Aleksandr Y. Aravkin, Felix J. Herrmann

Acquisition cost is a crucial bottleneck for seismic workflows, and low-rank formulations for data interpolation allow practitioners to `fill in' data volumes from critically subsampled data acquired in the field.

K-Algorithm A Modified Technique for Noise Removal in Handwritten Documents

no code implementations6 Jun 2013 Kanika Bansal, Rajiv Kumar

In the present paper, a modified technique for noise removal named as K-Algorithm has been proposed, which has two stages as filtering and binarization.

Fast methods for denoising matrix completion formulations, with applications to robust seismic data interpolation

no code implementations20 Feb 2013 Aleksandr Y. Aravkin, Rajiv Kumar, Hassan Mansour, Ben Recht, Felix J. Herrmann

In this paper, we consider matrix completion formulations designed to hit a target data-fitting error level provided by the user, and propose an algorithm called LR-BPDN that is able to exploit factorized formulations to solve the corresponding optimization problem.
