Image segmentation using the refinement indicators technique. (a) initial image to be segmented. (b) to (f) first iterations of the algorithm giving segmentations with successively 1, 2, 3, 6 and 10 homogeneous zones. |
The image segmentation problem can be viewed as an optimal control technique: the idea is to consider image segmentation as a parameter estimation problem. The parameter to estimate is the color of the pixels of the image. The adaptive parameterization technique builds iteratively an optimal representation of the parameter into uniform regions that form a partition of the domain, hence corresponding to a segmentation of the image (see Figure above). An error function is minimized during the iterations, and the partition of the image into regions is driven by the gradient of this error. The resulting segmentation algorithm inherits desirable properties from its optimal control origin: soundness, robustness, and flexibility.
The Ref-image user's manual is available on line.
You can also download the manual as DVI, PS, and PDF files.
The manual only exists in the English version, volunteers to translate it are warmly welcome...
You will need Objective Caml version 4.00 or higher to compile the sources, and the image OCaml library Grimage from the OCaml bazaar to link the program.
The OCaml image library Grimage, the OCaml user's additional library Ulib are also required to compile and link Ref-image. They are provided, and their configuration, compilation, and installation (in a private location) is fully automatic.
