1. Exploring the Trace Transform Joshua Stough COMP 255, December 1, 2003

2. The Idea (review) Some functional of a reparameterized image. The Key is: x*cos  + y*sin  = 

3. Dots transform to sine curves of phase and amplitude defined by tan -1 (y/x) and |(x,y)|, respectively

4. The Trace Transform for shape is the composition of dots

5. Basic Shapes and Their Transforms

6. Dominant Image Features are expressed in the Trace

10. Still to do Inverse: Draw the lines corresponding to a small subset of the Trace Image. Back projection. Other interesting functionals, including sensitive ones.
