rri_xy_orient_ui.m

绝对经典,老外制作的功能强大的matlab实现PLS_TOOBOX

%  Return orientation of the current image:
%	orient is orientation 1x2 matrix, in that:
%	Two elements represent: [x y]
%	Element value:	1 - Left to Right; 2 - Back to Front;
%			3 - Right to Left; 4 - Front to Back;
%  e.g.:
%	Standard RAS Orientation:	[1 2]
%	After rotating 180 degree:	[3 4]
