Function Documentation

int tl_find_best_object	(	tlPixelArray *	image,
		tlObject *	object,
		tlRect *	rect,
		int	increment
	)

Find the best match for a particular object in a given image; object and image have to be of the same format.

Parameters:

	image	the image to search
	object	the object to find
	rect	image portion to process
	increment	correlation increment [pix]
	object	[out] object location is updated

Returns:

confidence [%] on success, -1 otherwise.
See error management for details.

int tl_find_best_shape	(	tlPixelArray *	image,
		tlMask *	shape,
		tlRect *	rect,
		int	increment
	)

Find the best match for a particular shape in a given image.

Parameters:

	image	the BIN image to search
	shape	the shape mask
	rect	image portion to process
	increment	correlation increment [pix]
	shape	[out] shape location is updated

Returns:

confidence [%] on success, -1 otherwise.
See error management for details.

int tl_find_object	(	tlPixelArray *	image,
		tlObject *	object,
		int	confidence,
		tlRect *	rect,
		int	increment
	)

Find a match for a particular object in an image, given a minimum confidence threshold; object and image have to be of the same format.

Parameters:

	image	the image to search
	object	the object to find
	confidence	min match threshold [%]
	rect	image portion to process
	increment	correlation increment [pix]
	object	[out] object location is updated

Returns:

confidence [%] on success, -1 otherwise.
See error management for details.

int tl_find_shape	(	tlPixelArray *	image,
		tlMask *	shape,
		int	confidence,
		tlRect *	rect,
		int	increment
	)

Find a match for a particular shape in an image, given a minimum confidence threshold.

Parameters:

	image	the BIN image to search
	shape	the shape mask
	confidence	min match threshold [%]
	rect	image portion to process
	increment	correlation increment [pix]
	shape	shape location is updated

Returns:

confidence [%] on success, -1 otherwise.
See error management for details.
