Is KL transform same as PCA?

Answer is the Karhunen- Loeve Transform (KLT), also known as the Hotelling trans- form or Principal Component Analysis (PCA).

What is KL transform in image processing?

KL Transform or Principal Component Analysis (PCA) Unlike the other transforms covered so far this transform applies to random signals/images and has wide applications in data reduction, rotation and data decorrelation applications. Let x(n), n ∈ [0,N − 1] be a finite-extent 1-D random process with.
