Retinal vessel segmentation by improved matched filtering: evaluation on a new high-resolution fundus image database
Jan Odstrcilik,Radim Kolar,Attila Budai,Joachim Hornegger,Jiri Jan,Jiri Gazarek,Tomas Kubena,Pavel Cernosek,Ondrej Svoboda,Elli Angelopoulou +9 more
TL;DR: The concept of matched filtering is improved, and the proposed blood vessel segmentation approach is at least comparable with recent state-of-the-art methods, and outperforms most of them with an accuracy of 95% evaluated on the new database.
Journal ArticleDOI
Cell segmentation methods for label-free contrast microscopy: review and comprehensive comparison.
Tomas Vicar,Tomas Vicar,Jan Balvan,Jan Balvan,Josef Jaroš,Florian Jug,Radim Kolar,Michal Masarik,Michal Masarik,Jaromír Gumulec,Jaromír Gumulec +10 more
TL;DR: It is demonstrated that image reconstruction step allows the use of segmentation methods not originally intended for label-free imaging and validated suitable set of methods for each microscopy modality.

Journal ArticleDOI
Hybrid retinal image registration using phase correlation
TL;DR: The proposed method describes successful application of phase correlation method, which combines several basic steps — global correction of shift, rotation and scaling, detection of landmarks, their correspondences and finally image registration using second-order polynomial model.
Estimator Comparison of the Nakagami-m Parameter and its Application in Echocardiography
TL;DR: In this article, the comparison of various estimators of the m parameter from the Nakagami distribution has been conducted in biomedical engineering, particularly the ultrasound tissue characterization in the echocardiographic application.
