Impulse Denoising From Hyper-Spectral Images: A Blind Compressed Sensing Approach
Angshul Majumdar, Naushad Ansari, Hemant Aggarwal +1
In this work we propose a technique to remove sparse impulse noise from hyperspectral images. Our algorithm accounts for the spatial redundancy and spectral correlation of such ima…
M-RWTL: Learning Signal-Matched Rational Wavelet Transform in Lifting Framework
Naushad Ansari, Anubha Gupta
Transform learning is being extensively applied in several applications because of its ability to adapt to a class of signals of interest. Often, a transform is learned using a lar…
Statistical learning of rational wavelet transform for natural images
Naushad Ansari, Anubha Gupta
Motivated with the concept of transform learning and the utility of rational wavelet transform in audio and speech processing, this paper proposes Rational Wavelet Transform Learni…
Image Reconstruction using Matched Wavelet Estimated from Data Sensed Compressively using Partial Canonical Identity Matrix
Naushad Ansari, Anubha Gupta
This paper proposes a joint framework wherein lifting-based, separable, image-matched wavelets are estimated from compressively sensed (CS) images and used for the reconstruction o…
Design of Image Matched Non-Separable Wavelet using Convolutional Neural Network
Naushad Ansari, Anubha Gupta, Rahul Duggal
Image-matched nonseparable wavelets can find potential use in many applications including image classification, segmen- tation, compressive sensing, etc. This paper proposes a nove…
