Tracing Microtubules in Live Cell Images
Microtubule (MT) dynamics are traditionally analyzed from time lapse images by manual techniques that are laborious, approximate and often limited. Recently, computer vision techn...

Feasibility of Hough-Transform-Based Iris Localisation for Real-Time-Application
We present a fast method for locating iris features in frontal face images based on the Hough transform. It consists of an initial iris detection step and a tracking step which us...
