Applicability of oculomics for individual risk prediction: Repeatability and robustness of retinal Fractal Dimension using DART and AutoMorph

no code implementations11 Mar 2024 Justin Engelmann, Diana Moukaddem, Lucas Gago, Niall Strang, Miguel O. Bernabeu

In GRAPE, Pearson/Spearman correlation (first and next visit) was 0. 7479/0. 7474 for DART, and 0. 7109/0. 7208 for AutoMorph (all p<0. 0001).

QuickQual: Lightweight, convenient retinal image quality scoring with off-the-shelf pretrained models

1 code implementation25 Jul 2023 Justin Engelmann, Amos Storkey, Miguel O. Bernabeu

For this task, we present a second model, QuickQual MEga Minified Estimator (QuickQual-MEME), that consists of only 10 parameters on top of an off-the-shelf Densenet121 and can distinguish between gradable and ungradable images with an accuracy of 89. 18% (AUC: 0. 9537).

An open-source deep learning algorithm for efficient and fully-automatic analysis of the choroid in optical coherence tomography

1 code implementation3 Jul 2023 Jamie Burke, Justin Engelmann, Charlene Hamid, Megan Reid-Schachter, Tom Pearson, Dan Pugh, Neeraj Dhaun, Stuart King, Tom MacGillivray, Miguel O. Bernabeu, Amos Storkey, Ian J. C. MacCormick

Results: DeepGPET achieves excellent agreement with GPET on data from 3 clinical studies (AUC=0. 9994, Dice=0. 9664; Pearson correlation of 0. 8908 for choroidal thickness and 0. 9082 for choroidal area), while reducing the mean processing time per image on a standard laptop CPU from 34. 49s ($\pm$15. 09) using GPET to 1. 25s ($\pm$0. 10) using DeepGPET.

Robust and efficient computation of retinal fractal dimension through deep approximation

no code implementations12 Jul 2022 Justin Engelmann, Ana Villaplana-Velasco, Amos Storkey, Miguel O. Bernabeu

Thus, methods for calculating retinal traits tend to be complex, multi-step pipelines that can only be applied to high quality images.

Detection of multiple retinal diseases in ultra-widefield fundus images using deep learning: data-driven identification of relevant regions

1 code implementation11 Mar 2022 Justin Engelmann, Alice D. McTrusty, Ian J. C. MacCormick, Emma Pead, Amos Storkey, Miguel O. Bernabeu

Previous studies showed that deep learning (DL) models are effective for detecting retinal disease in UWF images, but primarily considered individual diseases under less-than-realistic conditions (excluding images with other diseases, artefacts, comorbidities, or borderline cases; and balancing healthy and diseased images) and did not systematically investigate which regions of the UWF images are relevant for disease detection.

Global explainability in aligned image modalities

no code implementations17 Dec 2021 Justin Engelmann, Amos Storkey, Miguel O. Bernabeu

We propose the pixel-wise aggregation of image-wise explanations as a simple method to obtain label-wise and overall global explanations.

Euler Characteristic Surfaces

1 code implementation16 Feb 2021 Gabriele Beltramo, Rayna Andreeva, Ylenia Giarratano, Miguel O. Bernabeu, Rik Sarkar, Primoz Skraba

While topological data analysis of higher-dimensional parameter spaces using stronger invariants such as homology continues to be the subject of intense research, Euler characteristic is more manageable theoretically and computationally, and this analysis can be seen as an important intermediary step in multi-parameter topological data analysis.
