1 Enhanced LIC Pencil Filter A project proposal by David Coyne

2 Authors’ earlier technique Line Integral Convolution produces pencil-like strokes Relies on segmentation (c), a challenging and computationally intensive problem

3 Authors’ earlier technique The original technique was slow because it required segmentation. it didn’t always distinguish areas well.

4 Concept of enhanced LIC Successive layers of strokes in different directions imitates actual technique. Finding layers of intensity range does not require segmentation of image regions

5 Steps for enhanced LIC Divide image into intensity layers

6 Steps for enhanced LIC Apply LIC, using texture orientation for darkest level vector field

7 Steps for enhanced LIC Add edges from edge detection Subtract paper samples for more realism

8 Risks Don’t know how to do Line Integral Convolution Determining texture direction Where to get digital paper samples

9 Weekly Milestones Nov. 24: Make LIC function Dec. 1: Represent vector fields in Matlab, Test LIC function on images and debug results Dec. 8: Implement texture direction and edge detection
