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

10b60f8d16 continuing refactoring ml samples; added "max vote" response to ANN_MLP. Probably, should make it in less hacky way 2014-07-31 14:12:10 +04:00

ba3783d205 initial commit; ml has been refactored; it compiles and the tests run well; some other modules, apps and samples do not compile; to be fixed 2014-07-29 23:54:23 +04:00

e433145b7e fix for Bug #3085: 
weights array is only allocated for (l_count+1) elements,
but then weights[l_count+1] element is accessed.

29b13ec1de Replaced most of the usages of parallel_for with that of parallel_for_. 
This should allow many algorithms to take advantage of more parallelization
technologies.

abeeb40d46 a big patch; use special proxy types (Input/OutputArray, Input/OutputArrayOfArrays) for passing in vectors, matrices etc. 2011-04-17 13:14:45 +00:00

65a7f13af3 replaced alloca() (a.k.a. cvStackAlloc) with AutoBuffer or vector() everywhere. cvStackAlloc() is still defined, but we do not need alloca() anymore to compile and run OpenCV (fixes #889 and may be some others) 2011-02-18 10:29:57 +00:00
