A step-by-step guide to reduce spatial coherence of laser light using a rotating ground glass diffuser
Tim Stangner, Hanqing Zhang, Tobias Dahlberg +2
Wide field-of-view imaging of fast processes in a microscope requires high light intensities motivating the use of lasers as light sources. However, due to their long spatial coher…
UmUTracker: A versatile MATLAB program for automated particle tracking of 2D light microscopy or 3D digital holography data
Hanqing Zhang, Tim Stangner, Krister Wiklund +2
We present a versatile and fast MATLAB program (UmUTracker) that automatically detects and tracks particles by analyzing video sequences acquired by either light microscopy or digi…
Circle detection using isosceles triangles sampling
Hanqing Zhang, Krister Wiklund, Magnus Andersson
Detection of circular objects in digital images is an important problem in several vision applications. Circle detection using randomized sampling has been developed in recent year…
