%  PROGRAM
% cparallel_classify - Classify an object using the Parallelepiped algorithm
%
%  DESCRIPTION
% This routine classifies an object using the Parallelepiped classification algorithm. The Parallelepiped algorithm is a simple, quick algorithm that assigns a class C to a pixel X if all values for the vector that represent X are inside the minimum and maximum values for the signature of C. More details about the Parallelepiped classifier are on the Classify Toolbox Manual.
% This routine requires an object to be classified (passed with the [-iimage] parameter) and a set of classes's signatures object created by "cparallel_signature" and appended by \fIkappend\fP (passed with the [-isigs] parameter). Output will be directed to the file specified by the parameter [-oclass]. The expected dimensions of the input and output objects are shown below:
% The input object which will be classified will have dimensions WxHxDxTxF, where F is the number of features. If it has mask, the masked points won't be classified, and the corresponding points in the output will have value 0 and mask 0.
% The input signatures must have dimensions Fx2x1xNx1, where N is the number of classes. It must be created by using "cparallel_signature" and \fIkappend\fP. 
% The output object will have dimensions WxHxDxTx1, and its value segment will have values on the range 0..N, where 0 means that the pixel was rejected. It will also have a corresponding mask segment with values 0 for the rejected pixels and 1 for the non-rejected pixels. The values for the pixels will be associated accordingly to the order the signatures were appended with "kappend".
% If a file is specified with the parameter [-oinfo], information about the classification for all points in the data will be written in ASCII in that file, which can get very large for large images.
% Please refer to the Classify toolbox manual or for one of the example workspaces for usage examples and details.
