Compression of Astronomical Images Based on the Karhunen - Loeve Transform
Original language description
The study deals with possibility of the Karhunen - Loeve Transform (KLT), also known as PCA (Principal Component Analysis), for astronomical data compression. This approach is based on analysis of statistical properties of these kinds of data. Image dataare divided into four groups - dark frame (DF), flat field (FF), light image (LI) and deep sky light image (DSLI). Quality measurement of the influence of loss part of the coder has been based on standard signal functions (mean square error - MSE, peaksignal to noise ratio PSNR), subjective quality measurement according to ITU standard (International Telecommunication Union) and the efficiency astronomical image processing.
