Simplified Active Calibration
Mehdi Faraji, Anup Basu
We present a new mathematical formulation to estimate the intrinsic parameters of a camera in active or robotic platforms. We show that the focal lengths can be estimated using onl…
Segmentation of Arterial Walls in Intravascular Ultrasound Cross-Sectional Images Using Extremal Region Selection
Mehdi Faraji, Irene Cheng, Iris Naudin +1
Intravascular Ultrasound (IVUS) is an intra-operative imaging modality that facilitates observing and appraising the vessel wall structure of the human coronary arteries. Segmentat…
A Simplified Active Calibration algorithm for Focal Length Estimation
Mehdi Faraji, Anup Basu
We introduce new linear mathematical formulations to calculate the focal length of a camera in an active platform. Through mathematical derivations, we show that the focal lengths…
EREL Selection using Morphological Relation
Yuying Li, Mehdi Faraji
This work concentrates on Extremal Regions of Extremum Level (EREL) selection. EREL is a recently proposed feature detector aiming at detecting regions from a set of extremal regio…
