Detailed Description

template<typename T>
class mimas::cgh_scene< T >

Use this class for generating multiple cornerwise histograms from a given input image (scene).

This tool can also be used for comparing / matching corner featuers in two scenes.

	)			`[inline]`

extract all corner features from the image.

threshold based on 'contrast_thres' to reduce the numbers a little. then create CGHs for all that remain. current implementation returns a maximum of 500 histograms, contrast ordered, with the strongest contrast corner first.

template<typename T>

cgh_wrapper_ptr_list mimas::cgh_scene< T >::crossCompare ( cgh_scene< T > & other ) [inline]

compare the histograms and provide output of the matches NOTE: nooooot symmetrical.

Search for the best match of all corners in the first image in the second image. Not necessarily back again. NOTE2: the output contains pointers to data which is 'owned' by the views. so don't delete the data pointed to in the returned list
