Usage instructions:

1. Compile TV code using compile_display.m or compile_no_display.m

2. Load 8 bit binary image into a variable u, for example,
   test_images/fork-4-1600x1200.gif or
   test_images/fork-4-800x600.gif

3. Calculate signature:

[u_out,ef,s,tmbs,lambda] = signature_full(u);

4. Or, calculate signature for normalized lambda:

[u_out,ef,s,tmbs,lambda_n] = signature_full_n(u,scale,l_0,l_n);

   scale, l_0, and l_n args are optional -- see signature_full_n.m

   * normalized S-signature: s/area_of_u

   * normalized signature: ef/sqrt(area_of_u)
