The Impact of KLT Coder on the Image Distortion in Astronomy

Popis výsledku v původním jazyce

Presented paper is devoted to the application of Karhunen-Lo?ve transform (KLT) for compression and to study of KLT impact on the image distortion in astronomy. This transform is an optimal fit for images with Gaussian probability density function in order to minimize the root mean square error (RMSE). The main part of the encoder is proposed in relation to statistical image properties. Selected astronomical image processing algorithms are used for the encoder testing. The astrometry and point spread function distortion are selected as the most important criteria. The results are compared with JPEG2000 standard. The KLT encoder provides better results from the RMSE point of view. These results are promising and show the novel approach to the design oflossy image compression algorithms and also suitability for algorithms of image data structuring for retrieving, transfer, and distribution.
