Bag of textons for image segmentation via soft clustering and convex shift
We propose an unsupervised image segmentation method based on texton similarity and mode seeking. The input image is first convolved with a filter-bank, followed by soft cluster...

To flock or not to flock: the pros and cons of flocking in long-range "migration" of mobile robot swarms
This study investigates the pros and cons of flocking in longrange “migration” of mobile robot swarms under the influence of different factors. We present a flocking behav...
