Improving Generalization Capability of Deep Learning-Based Nuclei Instance Segmentation by Non-deterministic Train Time and Deterministic Test Time Stain Normalization

no code implementations12 Sep 2023 Amirreza Mahbod, Georg Dorffner, Isabella Ellinger, Ramona Woitek, Sepideh Hatamikia

With the advent of digital pathology and microscopic systems that can scan and save whole slide histological images automatically, there is a growing trend to use computerized methods to analyze acquired images.

A global analysis of metrics used for measuring performance in natural language processing

1 code implementation nlppower (ACL) 2022 Kathrin Blagec, Georg Dorffner, Milad Moradi, Simon Ott, Matthias Samwald

Our results suggest that the large majority of natural language processing metrics currently used have properties that may result in an inadequate reflection of a models' performance.

CryoNuSeg: A Dataset for Nuclei Instance Segmentation of Cryosectioned H&E-Stained Histological Images

1 code implementation2 Jan 2021 Amirreza Mahbod, Gerald Schaefer, Benjamin Bancher, Christine Löw, Georg Dorffner, Rupert Ecker, Isabella Ellinger

Analysis of FS-derived H&E stained images can be more challenging as rapid preparation, staining, and scanning of FS sections may lead to deterioration in image quality.

A critical analysis of metrics used for measuring progress in artificial intelligence

no code implementations6 Aug 2020 Kathrin Blagec, Georg Dorffner, Milad Moradi, Matthias Samwald

Our results suggest that the large majority of metrics currently used have properties that may result in an inadequate reflection of a models' performance.

Investigating and Exploiting Image Resolution for Transfer Learning-based Skin Lesion Classification

no code implementations25 Jun 2020 Amirreza Mahbod, Gerald Schaefer, Chunliang Wang, Rupert Ecker, Georg Dorffner, Isabella Ellinger

Our results show that using very small images (of size 64x64 pixels) degrades the classification performance, while images of size 128x128 pixels and above support good performance with larger image sizes leading to slightly improved classification.
