Abstract
Methods and apparatus are provided for image analysis and modification using a fast sliding parabola erosion. The methods include selecting a scan line in an image and performing a unidirectional left-hand pass followed by a unidirectional right-hand pass. The unidirectional passes are performed as loops with increasing distance. By utilizing simple unidirectional left-hand and right-hand passes along a scan line in an image, the erosion procedure is greatly simplified and computation times are significantly reduced.
