Differences between image processing and other disciplines in the definition and the role of shape are explored. Diverse approaches to quantifying shape are reviewed. Attention is drawn to the need for close coupling between image acquisition and shape analysis. An example of the effect of the means of observation on dynamic shape extraction is drawn from linguistics. Current instrumentation fo...

An algorithm for the estimation of chin and cheek contours in video sequences is proposed. This algorithm exploits a priori knowledge about shape and position of chin and cheek contours in images. Exploiting knowledge about the shape, a parametric 2D model representing chin and cheek contours is introduced. Exploiting knowledge about the position, a MAP estimator is developed taking into accoun...

Full and high cheekbones are considered a desirable component of facial attractiveness. The aging process can result in a loss of facial volume and changes in facial contours. Cheek augmentation can replace lost facial volume, rejuvenate facial appearance, enhance cheek prominence, and improve facial symmetry. A new, highly purified, porcine-based collagen filler Dermicol-P35 #27G (Evolence; Or...
