Function Documentation

void ipts_corner_pyramid	(	const vimt_image_2d_of< float > &	image,
		vimt_image_pyramid &	corner_pyramid,
		vimt_image_pyramid &	smooth_pyramid,
		double	scale_step
	)

Compute corner strength at each level of a scale space pyramid.

Build smooth gaussian pyramid from the image, then compute corners at each level. Use ipts_scale_space_peaks() to get the position and scale of likely corners

void ipts_corner_pyramid	(	const vimt_image_pyramid &	smooth_pyramid,
		vimt_image_pyramid &	corner_pyramid
	)

Compute corner strength at each level of a scale space pyramid.

smooth_pyramid assumed to be of type float. Use ipts_scale_space_peaks() to get the position and scale of likely corners
