Spatially-Attentive Patch-Hierarchical Network with Adaptive Sampling for Motion Deblurring
Maitreya Suin, Kuldeep Purohit, A. N. Rajagopalan
This paper tackles the problem of motion deblurring of dynamic scenes. Although end-to-end fully convolutional designs have recently advanced the state-of-the-art in non-uniform mo…
Zero shot framework for satellite image restoration
Praveen Kandula, A. N. Rajagopalan
Satellite images are typically subject to multiple distortions. Different factors affect the quality of satellite images, including changes in atmosphere, surface reflectance, sun…
Unsupervised haze removal from underwater images
Praveen Kandula, A. N. Rajagopalan
Several supervised networks exist that remove haze information from underwater images using paired datasets and pixel-wise loss functions. However, training these networks requires…
Unsupervised network for low-light enhancement
Praveen Kandula, Maitreya Suin, A. N. Rajagopalan
Supervised networks address the task of low-light enhancement using paired images. However, collecting a wide variety of low-light/clean paired images is tedious as the scene needs…
Exploring the Effectiveness of Mask-Guided Feature Modulation as a Mechanism for Localized Style Editing of Real Images
Snehal Singh Tomar, Maitreya Suin, A. N. Rajagopalan
The success of Deep Generative Models at high-resolution image generation has led to their extensive utilization for style editing of real images. Most existing methods work on the…
Hybrid Transformer Based Feature Fusion for Self-Supervised Monocular Depth Estimation
Snehal Singh Tomar, Maitreya Suin, A. N. Rajagopalan
With an unprecedented increase in the number of agents and systems that aim to navigate the real world using visual cues and the rising impetus for 3D Vision Models, the importance…
Unfolding a blurred image
Kuldeep Purohit, Anshul Shah, A. N. Rajagopalan
We present a solution for the goal of extracting a video from a single motion blurred image to sequentially reconstruct the clear views of a scene as beheld by the camera during th…
Robust Unpaired Single Image Super-Resolution of Faces
Saurabh Goswami, Rajagopalan A. N
We propose an adversarial attack for facial class-specific Single Image Super-Resolution (SISR) methods. Existing attacks, such as the Fast Gradient Sign Method (FGSM) or the Proje…
Adaptive Image Inpainting
Maitreya Suin, Kuldeep Purohit, A. N. Rajagopalan
Image inpainting methods have shown significant improvements by using deep neural networks recently. However, many of these techniques often create distorted structures or blurry t…
Mitigating Channel-wise Noise for Single Image Super Resolution
Srimanta Mandal, Kuldeep Purohit, A. N. Rajagopalan
In practice, images can contain different amounts of noise for different color channels, which is not acknowledged by existing super-resolution approaches. In this paper, we propos…
Deep network for rolling shutter rectification
Praveen K, Lokesh Kumar T, A. N. Rajagopalan
CMOS sensors employ row-wise acquisition mechanism while imaging a scene, which can result in undesired motion artifacts known as rolling shutter (RS) distortions in the captured i…
IR Motion Deblurring
Nisha Varghese, Mahesh Mohan M. R., A. N. Rajagopalan
Camera gimbal systems are important in various air or water borne systems for applications such as navigation, target tracking, security and surveillance. A higher steering rate (r…
