Summary
I am Professor of Signal Processing in the Electrical and Electronic Engineering Department at Imperial College London. I am interested in mathematical methods for signal processing and high-dimensional data analysis. I apply these methods to develop interpretable model-based neural networks for computational imaging. The following articles and presentations highlight my recent research activities:
- Model-Based Deep Learning for Inverse Problems, Talk given at Imperial I-X, November 2023
- J. Huang and P.L. Dragotti, WINNet: Wavelet-inspired invertible network for image denoising IEEE Transactions on Image Processing, 2022
- P Song, H Verinaz-Jadan, CL Howe, AJ Foust, PL Dragotti, Light-Field Microscopy for the Optical Imaging of Neuronal Activity: When model-based methods meet data-driven approaches, IEEE Signal Processing Magazine 2022
- X. Deng and P.L. Dragotti, Deep Convolutional Neural Network for Multi-modal Image Restoration and Fusion, IEEE Transactions on Pattern Analysis and Machine Intelligence, 2020 (Software).
- R Alexandru, PL Dragotti, Reconstructing classes of non-bandlimited signals from time encoded information, IEEE Transactions on Signal Processing, 2019
