Quite often, the flame fronts are transient or weak and the images are noisy. The standard methods used in the field for the detection of flame fronts do not handle such data well. ...
A novel method for edge and line detection which is in the spirit of phase congruency but is based on a complex shearlet transform will be presented. ...
APPLICATIONS
Flame front detection For the task of flame front detection, we demonstrate the capabilities of the complex shearlet-based edge measure by processing a noisy mock image designed to represent ...
