Inputs
void	set_image (const char *image_fn)
	Set the input image. The image will be loaded from the specified filename.

void	set_image (const std::string &image_fn)
	Set the input image. The image will be loaded from the specified filename.

void	set_image (Plm_image *image)
	Set the input image as a Plm image.

void	set_image (const FloatImageType::Pointer image)
	Set the input image as an ITK image.

void	set_contrast_threshold (float contrast_threshold)
	Set the contrast threshold.

void	set_curvature_threshold (float curvature_threshold)
	Set the curvature threshold.

Outputs
itk::ScaleInvariantFeatureImageFilter< FloatImageType, 3 >::PointSetTypePointer	get_keypoints ()
	Return the detected keypoints. Unfortunately, the SIFT keypoints are not (yet) compatible with ordinary plastimatch (native or itk) pointsets.

void	save_pointset (const char *filename)
	Save the sift-detected points to a fcsv file.

Public Attributes
Sift_private *	d_ptr

Execution
void	run ()
	Compute SIFT feature locations in the input image.

static void	match_features (Sift &sift1, Sift &sift2, const char filename1, const char filename2, float match_ratio)
	Do feature matching, and write output to file. This should be a separate class.

◆ get_keypoints()

itk::ScaleInvariantFeatureImageFilter< FloatImageType, 3 >::PointSetTypePointer Sift::get_keypoints ( )

Return the detected keypoints. Unfortunately, the SIFT keypoints are not (yet) compatible with ordinary plastimatch (native or itk) pointsets.

◆ match_features()

void Sift::match_features	(	Sift &	sift1,
		Sift &	sift2,
		const char *	filename1,
		const char *	filename2,
		float	match_ratio
	)

static

Do feature matching, and write output to file. This should be a separate class.

◆ run()

void Sift::run ( )

Compute SIFT feature locations in the input image.

◆ save_pointset()

void Sift::save_pointset ( const char * filename )

Save the sift-detected points to a fcsv file.

◆ set_contrast_threshold()

void Sift::set_contrast_threshold ( float contrast_threshold )

Set the contrast threshold.

◆ set_curvature_threshold()

void Sift::set_curvature_threshold ( float curvature_threshold )

Set the curvature threshold.

◆ set_image() [1/4]

void Sift::set_image ( const char * image_fn )

Set the input image. The image will be loaded from the specified filename.

◆ set_image() [2/4]

void Sift::set_image ( const FloatImageType::Pointer image )

Set the input image as an ITK image.

◆ set_image() [3/4]

void Sift::set_image ( const std::string & image_fn )

Set the input image. The image will be loaded from the specified filename.

◆ set_image() [4/4]

void Sift::set_image ( Plm_image * image )

Set the input image as a Plm image.
