Digital Image Line Extraction and Edge Smoothing and Quality Analysis

The image line extraction and edge smoothing in general provides abstracted and stylized rendering of an image. It simplifies the visual interpretation of an image and convey certain features of it more effectively. In this project we are trying to develop a rendering technique that delivers a stylized abstraction of a digital image. Our approach is based on the filtering guided by a directional field that describes the flow of salient characteristics in the image. The line extraction and edge smoothing significantly improves the image quality in terms of feature improvement and image stylization.
