labelim.m

模式识别 MATLAB 的工具箱,比较实用,包括SVM,ICA,PCA,NN等等模式识别算法.

%LABELIM Construct image from objectlabels in case of feature images
%
%	IM = LABELIM(A)
%	IM = A*LABELIM
%
% If A is a dataset containing images stored as features, so
% each pixel is an object, than IM is the image containing the
% labels of the objects.
