Dgtal

Posted on September 26, 2011 by David Coeurjolly

* Global changes:
- A better decomposition of DGtal algorithms and
data structures into packages.
- By default, DGtal is built with minimal dependencies.
- Concepts and concept checking mechanism have been
considerably improved.

* Kernel Package: refactoring of Integer types considered in
DGtal.

* Topology Package: Interpixel/cellular topological model,
boundary tracking tools, ...

* Geometry Package:
- many things have been added in the 1D contour analysis module:
multi-modal representation of 1D contours and curves (GridCurve facade),
decomposition/segmentation into primitives, many differential
estimators added, helpers for multigrid comparison of estimators
- multigrid digital set generators from implicit and parametric
shapes in dimension 2.

* I/O Package: refactoring/enhancements of DGtal boards and
viewers, enhancement of 2D boards with libcairo and a new
Board3Dto2D board has been added.


* Tools: multigrid shapeGenerator/contourGenerator added,
lengthEstimator/estimatorComparator added for differential
estimator multigrid comparison, connected components extraction in
3D, ...

* Documentation: User guide has been improved thanks to a
decomposition of the library into packages.

* Kernel: global enhancement of different Integer types and
associated concepts.
* Topology: interpixel topology, cells, surface tracking
* Geometry2D: contour primitive decomposition, tangential cover,
convexity/concavity decomposition.
* GeometrynD: Reverse DT transformation (Euclidean)
* Infrastructure: 3D visualisation of DGtal objects with
libQGLViewer, shape factory

* Iterators added to PointVector
* Debug methods removed in Trace class
* Many bug fixes for VS compatibility

2010-05-15 dcoeurjo

implement a nice callback)
* Point and Vector templated classes added
* Space.*: skeleton of a DGtal::Space added

2010-03-03 dcoeurjo
* math/MeasureOfStraightLines: new class to compute the measure of a set
of Straight lines defined as a polygon in the (a,b) parameter space.
* test_measure: added

2010-02-17 dcoeurjo
* Trace: new class models for output streams in Trace class.
* TraceWriter/TraceWriterTerm/TraceWriterFile: added

2010-02-12 dcoeurjo
* models: bug fix in INLINE commands
* Trace/Clock: minor edit and bug report

2010-01-05 dcoeurjo
* Trace can be initialized on diffrent output stream (e.g. std::cerr or a file
stream)
* test_trace: update to test the new API

2010-01-04 dcoeurjo
* Clock: no more static variables and methods (in order to have several
running clocks)
* Trace: new interface and the endBlock displays and returns the
ellapsed time within the block

2009-12-28 dcoeurjo
* Trace: a new class to trace out messages to the standard output. Four type
of messages are possible: info, debug, error and "emphased". On
color linux terminal, messages appears with an appropriate color
foreground.
* test_trace: an illustration of the Trace interface

2009-12-14 dcoeurjo
* CMakeLists, test_clock updates to ensure compatibility with VisualStudio
* New cmake options
- OPTION(BUILD_SHARED_LIBS "Build shared libraries." ON)
- OPTION(BUILD_TESTS "Build tests." ON)

2009-12-11 dcoeurjo
* CMakeLists scripts and first backport from imagene (Clock class)

2009-12-11 dcoeurjo
* Repository cleanup:
- Modeles and genereateClass.sh removed
- JOL scripts & templates added


2009-12-03 dcoeurjo
