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.
