transform for analysis of cardiac function in myocardial gated SPECT.
The method we use is a natural extension of the classical Karhunen-Loeve
method (Karhunen, 1946; Loeve, 1945) and it is based on the orthogonal transformation which is a popular choice for geoscience analysis to reduce data dimensionality.
Depending on the field of application, it is also named the discrete Karhunen-Loeve
transform, the Hotelling transform or proper orthogonal decomposition (POD).
The forward and inverse discrete sine transforms are important functions used in digital signal processing applications especially in image compression due to the fact that they behave very much like the statistically optimal transform known to be Karhunen-Loeve
eigenvalue problems in cosmology: how should we tackle large data sets?

Here we will extend Sequential Karhunen-Loeve
 algorithm to make it suitable for updating SVD efficiently with mean update simultaneously.

But scientists at Kodak in Rochester, at the National Research Council of Canada and at the National Physical Laboratory in the UK took spectro-radiometric readings of the north sky at varying times and dates and the data were averaged and then fitted by NIST using a relatively new technology we now call Karhunen-Loeve
decomposition or proper orthogonal components or even principal components.
PCA is based on the Karhunen-Loeve
transform (the transformation).

2009b) also proposed to compress the SIFT descriptor with Karhunen-Loeve
transform, yielding approximate 2 bits per SIFT dimension.
