RE: [Vxl-maintainers] vxl meeting

[Ian S. <ian...@st...>]

Hi

Tim and I want to attend a VXL meeting. 

Before Mid December would be best for us.
We can fly to the US, preferably the East coast.

Some Agenda Items
* - Indicates ones we are prepared to put time in preparing for.

Relationship with ITK/Insight and VTK.
	We would like to know where ITK is going.


Candidates for promotion to VXL. *
	mbl_mz_random -> vnl
	mbl_priority_bound_queue -> vbl
	mbl_lru_cache -> vbl
	mbl_cloneable_ptr -> vbl
	mbl_gamma -> vnl
	mbl_matxvec -> vnl
	mbl_matrix_products -> vnl
	mbl_chord -> vil or vgl
	mbl_thin_plate_spline -> vgl_algo
	mbl_index_sort_cmp -> vbl
	mbl_stl -> vbl
	pdf1d, vpdfl -> vxl/pdf

	vipl, vepl -> vxl (After fixing the memory leaks,
	and adding documentation)


Get out a release.
	This is important from an "encouraging others to use
	VXL" point of view.


VNL
	Several people (including as I recall, Bill Hoffman)
	have complained about the fact that vcl_vector_fixed
	is non-optimal. A 2 element vector needs 3 elements of
	storage (1 for n_dims_)
	Options include using MTL, TNT, or upgrading VNL.


VIL *
	We would like to retrofit VIL with some of mil's
	features, e.g.
	Merge concepts of planes and channels.
		(i.e. assert nplanes == 1 || nchannels == 1)
	Using pointer arithmetic based addressing in
		vil_memory_image.
	vil_memory_image_impl should know its type at compile
		time
	Addition of standard polymorphic image and world2image
		transform type. Could be a specialised vcl_pair.


Documentation
	Is anyone prepared to write some more.
	e.g. for vgl and vcsl.


Testing *
	The Dart system is great - but it points out that some
	of our testing coverage is pretty poor.


Using more external libraries
	OpenCV
	Boost - which has
		random number generators
		lambda notation for inline functions
		all sorts of smart pointers
		compile-time concept checking for generic
			programming,
		is likely to be added in part to the STL.
