0bc9a0db18 Improvement of sequential connected components Wu's algorithm and provide parallel version of both Wu's and Grana's algorithms (using TBB library) 2016-11-22 11:42:13 +01:00

5ddd25313f Add Grana's connected components algorithm for 8-way connectivity. (#6823)
* Add Grana's connected components algorithm for 8-way connectivity. That algorithm is faster than Wu's one (currently implemented in opencv). For more details see https://github.com/prittt/YACCLAB.

* New functions signature and distance transform compatibility

* Add tests to imgproc/test/test_connectedcomponents.cpp

* Change of test_connectedcomponents.cpp for c++98 support

8a4a1bb018 Several type of formal refactoring:
1. someMatrix.data -> someMatrix.prt()
2. someMatrix.data + someMatrix.step * lineIndex -> someMatrix.ptr( lineIndex )
3. (SomeType*) someMatrix.data -> someMatrix.ptr<SomeType>()
4. someMatrix.data -> !someMatrix.empty() ( or !someMatrix.data -> someMatrix.empty() ) in logical expressions

affab4f156 correct range computations, it is difficult to do the more efficient single pass 3N/2 implementations correctly in this particular setting without costing more than they save 2013-08-27 00:34:22 -07:00

00bdca7684 A few changes to comply with upstream requirements for merge.
-Change input/output order from (out Labeled, in Image) -> (in Image, Out Labeled) and convert
to Input/OutputArrays in the process.

-Adopt OutputArray for statistics export so that the algorithm is "wrapper friendly" and not requiring a new struct in
language bindings at the expense of using doubles for everything and slowing statistics computation down..

d5aa679d3f adjust output type to return int32... it should at least be unsigned but this breaks python bindings;
remove non-8bit input type support, not worth the binary size
