Selected work spanning generative restoration, aerial imaging, scientific data and applied machine learning.

GenR
Akbar Ali, Indra Deep Mastan, Shanmuganathan Raman.
Pattern Recognition Letters, Elsevier — 2026

A degradation-agnostic face restoration method that optimises in the latent space of a pretrained generator, handling denoising, deblurring and inpainting without retraining per degradation.

Unsupervised Image Deblurring in Latent Space using Pivotal Tuning Inversion
Akbar Ali, Indra Deep Mastan, Shanmuganathan Raman.
Under review — 2026

Pivotal tuning inversion anchors a blurred observation to a generator's latent manifold, recovering sharp detail without paired supervision or a known blur kernel.

ZS-CLIP2Clean: Zero-Shot CLIP-Guided Training-Free Single-Image Denoising
Abhiyodaya Pandey, Akbar Ali, Indra Deep Mastan, Shanmuganathan Raman.
Under review — 2026

Denoising a single image with no training and no clean reference, using CLIP as a semantic critic to steer restoration towards a perceptually faithful result.

InscriptionOCR: A Dataset and Method for Understanding Inscriptions
Jaidev Sanjay Khalane, Akbar Ali, V. N. Prabhakar, Shanmuganathan Raman.
Under review — 2026

A dataset and recognition pipeline for historical stone inscriptions, where weathering and archaic glyph forms break standard scene-text OCR.

Akbar Ali, Indra Deep Mastan, Shanmuganathan Raman.
IEEE ICIP — 2025

A stress test of unsupervised StyleGAN restoration under degradations it was never tuned for, showing where latent-space optimisation holds up and where it silently fails.

Akbar Ali, Pankaj Khanna, Subramanian Sankaranarayanan, Shanmuganathan Raman.
IEEE ICIP — 2025

An aerial and ground image dataset covering a full cotton growth cycle from weekly drone missions at 10 m, 15 m and 115 m, for crop health and pest analysis.

Akbar Ali, Ranjit Kumar Rout, Saiyed Umer.
Springer Nature — 2023

A predictive framework for Parkinson's disease analysis pairing classification accuracy with descriptive feature analysis so clinicians can see which measurements drive each prediction.
