We focus on algorithms for extracting straight edge lines and for determining distances between known objects in grey scale images. We are using the following algorithms mostly in real time implementations: 
  • Contour Tracer
  • Canny filter [1]
  • Standard operators like Kirsch-, LoG-, Gradient- and Median -operators
  • Template Matching
Determining the center of a gear of a wrist watch for assembly purpose.
