void | saveWindowParameters (const String &windowName) |
Saves parameters of the specified window. | |
void | scaleAdd (InputArray src1, double alpha, InputArray src2, OutputArray dst) |
Calculates the sum of a scaled array and another array. | |
void | Scharr (InputArray src, OutputArray dst, int ddepth, int dx, int dy, double scale=1, double delta=0, int borderType=BORDER_DEFAULT) |
Calculates the first x- or y- image derivative using Scharr operator. | |
void | seamlessClone (InputArray src, InputArray dst, InputArray mask, Point p, OutputArray blend, int flags) |
Image editing tasks concern either global changes (color/intensity corrections, filters, deformations) or local changes concerned to a selection. Here we are interested in achieving local changes, ones that are restricted to a region manually selected (ROI), in a seamless and effortless manner. The extent of the changes ranges from slight distortions to complete replacement by novel content. | |
Rect | selectROI (const String &windowName, InputArray img, bool showCrosshair=true, bool fromCenter=false) |
Selects ROI on the given image. Function creates a window and allows user to select a ROI using mouse. Controls: use space or enter to finish selection, use key c to cancel selection (function will return the zero cv::Rect). | |
Rect | selectROI (InputArray img, bool showCrosshair=true, bool fromCenter=false) |
void | selectROIs (const String &windowName, InputArray img, std::vector< Rect > &boundingBoxes, bool showCrosshair=true, bool fromCenter=false) |
Selects ROIs on the given image. Function creates a window and allows user to select a ROIs using mouse. Controls: use space or enter to finish current selection and start a new one, use esc to terminate multiple ROI selection process. | |
void | sepFilter2D (InputArray src, OutputArray dst, int ddepth, InputArray kernelX, InputArray kernelY, Point anchor=Point(-1,-1), double delta=0, int borderType=BORDER_DEFAULT) |
Applies a separable linear filter to an image. | |
bool | setBreakOnError (bool flag) |
Sets/resets the break-on-error mode. | |
void | setIdentity (InputOutputArray mtx, const Scalar &s=Scalar(1)) |
Initializes a scaled identity matrix. | |
void | setMouseCallback (const String &winname, MouseCallback onMouse, void *userdata=0) |
Sets mouse handler for the specified window. | |
void | setNumThreads (int nthreads) |
OpenCV will try to set the number of threads for the next parallel region. | |
void | setOpenGlContext (const String &winname) |
Sets the specified window as current OpenGL context. | |
