Siamese Content-based Search Engine for a More Transparent Skin and Breast Cancer Diagnosis through Histological Imaging

no code implementations16 Jan 2024 Zahra Tabatabaei, Adrián Colomer, Javier Oliver Moll, Valery Naranjo

The Breast-twins model achieves 70% of the F1score at the top first, which exceeds the other state-of-the-art methods at a higher amount of K such as 5 and 400.

Attention to detail: inter-resolution knowledge distillation

2 code implementations11 Jan 2024 Rocío del Amor, Julio Silva-Rodríguez, Adrián Colomer, Valery Naranjo

The development of computer vision solutions for gigapixel images in digital pathology is hampered by significant computational limitations due to the large size of whole slide images.

WWFedCBMIR: World-Wide Federated Content-Based Medical Image Retrieval

no code implementations5 May 2023 Zahra Tabatabaei, Yuandou Wang, Adrián Colomer, Javier Oliver Moll, Zhiming Zhao, Valery Naranjo

The study shows that the FedCBMIR method increases the F1-Score (F1S) of each client to 98%, 96%, 94%, and 97% in the BreaKHis experiment with a generalized model of four magnifications and does so in 6. 30 hours less time than total local training.

A self-training framework for glaucoma grading in OCT B-scans

no code implementations23 Nov 2021 Gabriel García, Adrián Colomer, Rafael Verdú-Monedero, José Dolz, Valery Naranjo

Particularly, the proposed two-step learning methodology resorts to pseudo-labels generated during the first step to augment the training dataset on the target domain, which is then used to train the final target model.

Circumpapillary OCT-Focused Hybrid Learning for Glaucoma Grading Using Tailored Prototypical Neural Networks

no code implementations25 Jun 2021 Gabriel García, Rocío del Amor, Adrián Colomer, Rafael Verdú-Monedero, Juan Morales-Sánchez, Valery Naranjo

Glaucoma is one of the leading causes of blindness worldwide and Optical Coherence Tomography (OCT) is the quintessential imaging technique for its detection.

WeGleNet: A Weakly-Supervised Convolutional Neural Network for the Semantic Segmentation of Gleason Grades in Prostate Histology Images

1 code implementation21 May 2021 Julio Silva-Rodríguez, Adrián Colomer, Valery Naranjo

Regarding the estimation of the core-level Gleason score, we obtained a k of 0. 76 and 0. 67 between the model and two different pathologists.

Semantic Segmentation

Self-learning for weakly supervised Gleason grading of local patterns

1 code implementation21 May 2021 Julio Silva-Rodríguez, Adrián Colomer, Jose Dolz, Valery Naranjo

Particularly, the proposed model brings an average improvement on the Cohen's quadratic kappa (k) score of nearly 18% compared to full-supervision for the patch-level Gleason grading task.

Analysis of Hand-Crafted and Automatic-Learned Features for Glaucoma Detection Through Raw Circmpapillary OCT Images

no code implementations9 Sep 2020 Gabriel García, Adrián Colomer, Valery Naranjo

Taking into account that glaucoma is the leading cause of blindness worldwide, we propose in this paper three different learning methodologies for glaucoma detection in order to elucidate that traditional machine-learning techniques could outperform deep-learning algorithms, especially when the image data set is small.
