* Introduction
** Acsegmentor aims at segmenting an image into homogenenous regions.
** Use `acsegmentor --help' to find the (numerous) available command line options

* Segmentation examples
[@
$ acsegmentor --image lena.pgm --output output.pgm
=> segment the image lena, resulting segmentation is in `output.pgm'.
=> use default parameters: a contrario segmentation with MergeBest
exploration heuristic and watershed initialization with sigma=0.8

$ acsegmentor --image lena.pgm --output output.pgm --initializer egbis
=> idem as above with an egbis initialization with default parameters
(k=50, sigma=0.8).

$ acsegmentor --image bigimage.pgm --output output.pgm
=> Exception raised because no thresholds can be found.
=> Thresholds were pre-computed for some standard image sizes
256x256, 384x256 and 512x512. For other sizes, you have to
learn new thresholds (see LEARNING EXAMPLES).

$ acsegmentor --image bigimage.pgm --output output.pgm --sigma 1.1
=> Exception raised because no thresholds can be found.
=> Specific thresholds must be computed for each parameter.
Pre-computed thresholds are given only for default parameters.
=> You have to run a learning process.

$ acsegmentor --image bigimage.pgm --output output.pgm \
--threshold-database thresholds.xml
=> Read additional thresholds from `thresholds.xml'. These
thresholds can be generated automatically by the learning phase.
@]

* Learning examples
[@
$ acsegmentor --threshold-database-output thresholds.xml \
--width 1024 --height 1024 --initializer egbis \
--nb-iterations 1000
=> Learn thresholds for 1024x1024 images for an egbis initializer.
=> 1000 images will be analyzed to deduce statistical thresholds.
=> Resulting thresholds will be put into `thresholds.xml'. This file
can then be used to segment new 1024x1024 images.

Acsegmentor aims at segmenting gray-level images into homogeneous regions. It's a generic algorithm: it requires a distance function between regions, an exploration heuristic and automatically find thresholds ensuring that regions in the final partitions will be statistically meaningfully different. This step is done using ''a contrario'' reasoning: two regions are meaningfully different is the probability that the exploration heuristic find such different regions in pure noise is very low. This ensures that in the final partition, statistically, regions difference are not due to chance but are a result of some physical phenomena, such as different objects in the scene.

=> Type 'c' (configure, maybe twice)

both optimizations and debugging symbols,
enter `RelWithDebInfo' in CMAKE_BUILD_TYPE. For the fastest binaries,
enter `Release'.
