Abstract
This paper presents a new deformable model for object detection,
based on charged particle dynamics and geometric contour
propagation, applied to the segmentation of the left ventricle of
the heart in SPECT images. The model detects object boundaries with
a charged active contour that propagates under the influence of
Lorentz forces in an image-based electrostatic field.
We find positions of vector field divergence for automatic
initialisation of the contour. Experimental results on a dataset of
160 images are evaluated against hand-labelled groundtruth data.
