da03e4e910 Fixes from pull of cleanups: clang tidied, reviewed, fixed new bugs, undeleted needed code. Probably breaks the build, due to some inclusion of changes in utf8/32 conversion 2017-07-14 09:30:14 -07:00

1cf8fe51a0 Remove mathfix.h 
It was only needed for MS Visual Studio 2012 and older.
Those compilers are not supported for Tesseract.

562de89728 Reduce number of new / delete operations for class KDTreeSearch 
Add also several TODO comments because it is not clear why expensive
FLOAT64 calculations are used instead of cheaper FLOAT32 ones.

83588bc7a1 Classify: Avoid unneeded new / delete operations 
Both class variables BaselineCutoffs and CharNormCutoffs were pointers
to fixed size arrays which were allocated in the constructor and
deallocated in the destructor. These two extra allocations and two
extra deallocations can be avoided.

1cc511188d Added extra Init that takes a memory buffer or a filereader function pointer to enable read of traineddata from memory or foreign file systems. Updated existing readers to use TFile API instead of FILE. This does not yet add big-endian capability to LSTM, but it is very easy from here. 2017-04-27 15:48:23 -07:00

1e60a8d71c Fix crash caused by undefined value of local variable 
Commit b1f03cb697 added a call of function
FreeFeatureSet to fix a memory leak, but introduced a new bug because the
local variable FloatFeatures was not always assigned a value.

Now FloatFeatures is always assigned a value, and we only need a single
place where FreeFeatureSet is called.
