Digital Image Special Effects----
Project Proposal for EE368: Digital Image Processing 
              by Feng Xiao

This project aims to understand and simulate some digital image special 
effects by applying some basic concepts learned from class. I will try to
 understand the fun part of image processing. 

This project will include following parts:
  1. A small interactive digital warping package which exploits the concept
 of geometrical transformation and different kinds of interpolations. It 
will allows users to warp and un-warp any part of an image. 
  2. Depend on the progress that I can make, I will try to implement and 
develop algorithms for automatically generating non-photorealistic pictures 
from images. Some special effects are theoretically simply. For example, 
'Negative' and 'Emboss' use very simple shift-invariant linear filter, 
'Underpainting Oil Painting Effect' uses the histogram information of image.
 For some effects, like 'Watercolor Effect', there are only some very 
complicated algorithm which try to simulate the physical property of brush 
and paper. For others like 'Colored Pen' and 'Charcoal Effect', there are 
no publications. Since there are some commercial software have implemented 
most of the special effects mentioned above, I will try to understand and 
simulate as several of them in the framework of some simple non-linear 
'area operation'. This part is more open-ended, but will be even more 
helpful for me to understand image processing.

Estimated works:

Part 1 may require 10-15 hours work.
Part 2 may require 30-50 hours work.
