Function Documentation

void ActCvDeInit

(

)

stop the video processing thread

Definition at line 331 of file server-main.cpp.

References bgThread, exitFlag, and threadMutex.

Referenced by TestLines(), TestMatch(), and TestText().

void ActCvInit

(

)

start the video processing thread

Todo:

error handling when there's already a thread running

Definition at line 307 of file server-main.cpp.

References BGFunc(), bgThread, exitFlag, MHDBGMSG, and threadMutex.

Referenced by TestLines(), TestMatch(), and TestText().

void AddRecognition

(

cv_algorithm

a)

add an algorithm to the list of currently used algorithms

Definition at line 375 of file server-main.cpp.

References AddRecognitionInternal(), jobs, MHDBGMSG, and mhthreads::Condition::Wait().

Referenced by TestLines(), TestMatch(), and TestText().

int FindFirstLine

(

)

start the line data exchange

Returns

handle for subsequent calls to FindNextLine and LineFindFinish. 0 on error.

If FindFirstLine returns a handle, you must call LineFindFinish to release internal memory structures.

Warning

not threadsafe

Referenced by TestLines().

int FindFirstMatch

(

)

start the image matching result exchange

Returns

handle for subsequent calls to FindNextMatch and MatchFindFinish. 0 on error.

If FindFirstMatch returns a handle, you must call MatchFindFinish to release internal memory structures.

Warning

not threadsafe
