- Wait a minute...
- If the original image is 100x100, then to 200x200 image the
- edges or such must be estimated -- but can do it independently to
- jpg or any image.
-
- Even you saw details in 200x200 fractal compressed image, the
- actual image may not contain those details.
-
- But because fractal system (IFS) simulates real objects (like tree)
- appropriately, you may get just simulated details to image.
-
-
- So, what is the current method to make fractal compression?
- Does it use collage theorem (i.e. ready made simulated objects or
- such).
