Sub-Aperture Feature Adaptation in Single Image Super-resolution Model for Light Field Imaging

no code implementations25 Jul 2022 Aupendu Kar, Suresh Nehra, Jayanta Mukhopadhyay, Prabir Kumar Biswas

However, the spatial resolution is significantly constrained in commercial microlens based LF cameras because of the inherent multiplexing of spatial and angular information.

Zero-Shot Single Image Restoration Through Controlled Perturbation of Koschmieder's Model

no code implementations CVPR 2021 Aupendu Kar, Sobhan Kanti Dhara, Debashis Sen, Prabir Kumar Biswas

Our zero-shot network estimates the parameters of the Koschmieder's model, which describes the degradation in the input image, to perform image restoration.

Progressive Update Guided Interdependent Networks for Single Image Dehazing

1 code implementation4 Aug 2020 Aupendu Kar, Sobhan Kanti Dhara, Debashis Sen, Prabir Kumar Biswas

The estimated parameters are then used to guide our dehazing module, where the estimates are progressively updated by novel convolutional networks.

Fast Bayesian Uncertainty Estimation and Reduction of Batch Normalized Single Image Super-Resolution Network

1 code implementation CVPR 2021 Aupendu Kar, Prabir Kumar Biswas

Furthermore, this paper proposes an approach to reduce the model's uncertainty for an input image, and it helps to defend the adversarial attacks on the image super-resolution model.
