Initialize the different displays.

Parameters

[out]	Iinput	Input image of the program.
[out]	IcannyVisp	Image resulting from the vpCannyEdgeDetection method.
[out]	p_dIx	If different from nullptr, pointer towards the gradient along the horizontal axis.
[out]	p_dIy	If different from nullptr, pointer towards the gradient along the vertical axis.
[out]	p_IcannyimgFilter	If different from nullptr, pointer towards the result of the vpImageFilter::canny method.

waitForClick()

bool drawingHelpers::waitForClick	(	const vpImage< unsigned char > &	I,
		const bool &	blockingMode
	)

Catch the user clicks to know if the user wants to stop the program.

Parameters

[in]	I	The gray-scale image to display.
[in]	blockingMode	If true, wait for a click to switch to the next image.

Returns

true The user wants to continue the application.

false The user wants to stop the application.
