◆ CV_Error

#define CV_Error	(	code,
		msg
	)	cv::error( code, msg, CV_Func, __FILE__, __LINE__ )

Call the error handler.

Currently, the error handler prints the error code and the error message to the standard error stream stderr. In the Debug configuration, it then provokes memory access violation, so that the execution stack and all the parameters can be analyzed by the debugger. In the Release configuration, the exception is thrown.

引数

code	one of Error::Code
msg	error message

◆ CV_Error_

#define CV_Error_	(	code,
		args
	)	cv::error( code, cv::format args, CV_Func, __FILE__, __LINE__ )

Call the error handler.

This macro can be used to construct an error message on-fly to include some dynamic information, for example:

// note the extra parentheses around the formatted text message
CV_Error_(Error::StsOutOfRange,
("the value at (%d, %d)=%g is out of range", badPt.x, badPt.y, badValue));

引数

code	one of Error::Code
args	printf-like formatted error message in parentheses

◆ alignPtr()

template<typename _Tp >

static _Tp * cv::alignPtr	(	_Tp *	ptr,
		int	n = `(int)sizeof(_Tp)`
	)

inlinestatic

Aligns a pointer to the specified number of bytes.

The function returns the aligned pointer of the same type as the input pointer:

$\texttt{(_Tp*)(((size_t)ptr + n-1) & -n)}$

引数

ptr	Aligned pointer.
n	Alignment size that must be a power of two.

◆ alignSize()

static size_t cv::alignSize	(	size_t	sz,
		int	n
	)

inlinestatic

Aligns a buffer size to the specified number of bytes.

The function returns the minimum number that is greater than or equal to sz and is divisible by n :

$\texttt{(sz + n-1) & -n}$

引数

sz	Buffer size to align.
n	Alignment size that must be a power of two.

◆ checkHardwareSupport()

CV_EXPORTS_W bool cv::checkHardwareSupport ( int feature )

Returns true if the specified feature is supported by the host hardware.

The function returns true if the host hardware supports the specified feature. When user calls setUseOptimized(false), the subsequent calls to checkHardwareSupport() will return false until setUseOptimized(true) is called. This way user can dynamically switch on and off the optimized code in OpenCV.

引数

feature The feature of interest, one of cv::CpuFeatures

引数

x	x-coordinate of the vector.
y	y-coordinate of the vector.

◆ fastFree()

CV_EXPORTS void cv::fastFree ( void * ptr )

Deallocates a memory buffer.

The function deallocates the buffer allocated with fastMalloc . If NULL pointer is passed, the function does nothing. C version of the function clears the pointer pptr to avoid problems with double memory deallocation.

引数

ptr	Pointer to the allocated buffer.

◆ fastMalloc()

CV_EXPORTS void * cv::fastMalloc ( size_t bufSize )

Allocates an aligned memory buffer.

The function allocates the buffer of the specified size and returns it. When the buffer size is 16 bytes or more, the returned buffer is aligned to 16 bytes.

引数

◆ getBuildInformation()

CV_EXPORTS_W const String & cv::getBuildInformation ( )

Returns full configuration time cmake output.

Returned value is raw cmake output including version control system revision, compiler version, compiler flags, enabled modules and third party libraries, etc. Output format depends on target architecture.

◆ getCPUFeaturesLine()

CV_EXPORTS_W std::string cv::getCPUFeaturesLine ( )

Returns list of CPU features enabled during compilation.

Returned value is a string containing space separated list of CPU features with following markers:

no markers - baseline features
prefix * - features enabled in dispatcher
suffix ? - features enabled but not available in HW

Example: SSE SSE2 SSE3 *SSE4.1 *SSE4.2 *FP16 *AVX *AVX2 *AVX512-SKX?

◆ getCPUTickCount()

CV_EXPORTS_W int64 cv::getCPUTickCount ( )

Returns the number of CPU ticks.

The function returns the current number of CPU ticks on some architectures (such as x86, x64, PowerPC). On other platforms the function is equivalent to getTickCount. It can also be used for very accurate time measurements, as well as for RNG initialization. Note that in case of multi-CPU systems a thread, from which getCPUTickCount is called, can be suspended and resumed at another CPU with its own counter. So, theoretically (and practically) the subsequent calls to the function do not necessary return the monotonously increasing values. Also, since a modern CPU varies the CPU frequency depending on the load, the number of CPU clocks spent in some code cannot be directly converted to time units. Therefore, getTickCount is generally a preferable solution for measuring execution time.

◆ getHardwareFeatureName()

CV_EXPORTS_W String cv::getHardwareFeatureName ( int feature )

Returns feature name by ID

Returns empty string if feature is not defined

◆ getNumThreads()

CV_EXPORTS_W int cv::getNumThreads ( )

Returns the number of threads used by OpenCV for parallel regions.

Always returns 1 if OpenCV is built without threading support.

The exact meaning of return value depends on the threading framework used by OpenCV library:

TBB - The number of threads, that OpenCV will try to use for parallel regions. If there is any tbb::thread_scheduler_init in user code conflicting with OpenCV, then function returns default number of threads used by TBB library.
OpenMP - An upper bound on the number of threads that could be used to form a new team.
Concurrency - The number of threads, that OpenCV will try to use for parallel regions.
GCD - Unsupported; returns the GCD thread pool limit (512) for compatibility.
C= - The number of threads, that OpenCV will try to use for parallel regions, if before called setNumThreads with threads > 0, otherwise returns the number of logical CPUs, available for the process.
参照
setNumThreads, getThreadNum

◆ getThreadNum()

CV_EXPORTS_W int cv::getThreadNum ( )

Returns the index of the currently executed thread within the current parallel region. Always returns 0 if called outside of parallel region.

非推奨:: Current implementation doesn't corresponding to this documentation.

The exact meaning of the return value depends on the threading framework used by OpenCV library:

TBB - Unsupported with current 4.1 TBB release. Maybe will be supported in future.
OpenMP - The thread number, within the current team, of the calling thread.
Concurrency - An ID for the virtual processor that the current context is executing on (0 for master thread and unique number for others, but not necessary 1,2,3,...).
GCD - System calling thread's ID. Never returns 0 inside parallel region.
C= - The index of the current parallel task.

◆ saturate_cast() [8/11]

template<typename _Tp >

static _Tp cv::saturate_cast ( uchar v )

inlinestatic

Template function for accurate conversion from one primitive type to another.

The function saturate_cast resembles the standard C++ cast operations, such as static_cast<T>() and others. It perform an efficient and accurate conversion from one primitive type to another (see the introduction chapter). saturate in the name means that when the input value v is out of the range of the target type, the result is not formed just by taking low bits of the input, but instead the value is clipped. For example:

uchar a = saturate_cast<uchar>(-100); // a = 0 (UCHAR_MIN)

short b = saturate_cast<short>(33333.33333); // b = 32767 (SHRT_MAX)

Such clipping is done when the target type is unsigned char , signed char , unsigned short or signed short . For 32-bit integers, no clipping is done.

When the parameter is a floating-point value and the target type is an integer (8-, 16- or 32-bit), the floating-point value is first rounded to the nearest integer and then clipped if needed (when the target type is 8- or 16-bit).

引数

v	Function parameter.

◆ setBreakOnError()

CV_EXPORTS bool cv::setBreakOnError ( bool flag )

Sets/resets the break-on-error mode.

When the break-on-error mode is set, the default error handler issues a hardware exception, which can make debugging more convenient.

戻り値: the previous state

◆ setNumThreads()

CV_EXPORTS_W void cv::setNumThreads ( int nthreads )

OpenCV will try to set the number of threads for the next parallel region.

If threads == 0, OpenCV will disable threading optimizations and run all it's functions sequentially. Passing threads < 0 will reset threads number to system default. This function must be called outside of parallel region.

OpenCV will try to run its functions with specified threads number, but some behaviour differs from framework:

TBB - User-defined parallel constructions will run with the same threads number, if another is not specified. If later on user creates his own scheduler, OpenCV will use it.
OpenMP - No special defined behaviour.
Concurrency - If threads == 1, OpenCV will disable threading optimizations and run its functions sequentially.
GCD - Supports only values <= 0.
C= - No special defined behaviour.
引数

nthreads Number of threads used by OpenCV.

参照
getNumThreads, getThreadNum

◆ setUseOptimized()

CV_EXPORTS_W void cv::setUseOptimized ( bool onoff )

Enables or disables the optimized code.

The function can be used to dynamically turn on and off optimized dispatched code (code that uses SSE4.2, AVX/AVX2, and other instructions on the platforms that support it). It sets a global flag that is further checked by OpenCV functions. Since the flag is not checked in the inner OpenCV loops, it is only safe to call the function on the very top level in your application where you can be sure that no other OpenCV function is currently executed.

By default, the optimized code is enabled unless you disable it in CMake. The current status can be retrieved using useOptimized.

引数

onoff The boolean flag specifying whether the optimized code should be used (onoff=true) or not (onoff=false).

◆ useOptimized()

CV_EXPORTS_W bool cv::useOptimized ( )

Returns the status of optimized code usage.

The function returns true if the optimized code is enabled. Otherwise, it returns false.
