Answer 1

PCA:

[COEFF,SCORE] = princomp(YourImage);

LDA: use classify

[Karan Ratnaparkhi]

Hey walter

[COEFF,SCORE] = princomp(YourImage); is showing me error

??? Undefined function or method 'princomp' for input arguments of type 'double'.

Error in ==> algo4 at 3

[COEFF,SCORE] = princomp(b);

even for uint8

[Walter Roberson]

And do you have the Statistics toolbox installed and licensed?

[Karan Ratnaparkhi]

nope!!

[Walter Roberson]

The MATLAB routines for PCA and LDA are part of the {optional, extra cost} Statistics Toolbox.

I imagine that if you were to use a search engine, you would be able to find alternative code Files that other people have Contributed for the Exchange of MATLAB ideas.
