The Lossy Compression Technique Based on KLT
Original language description
A higher and better precision can been achieved while using more recent observation techniques and superior detection sensors. It has brought a very rapid increase of data amount as a result. The high spatial resolution (up to ten million pixels) and a high bit level grey scale images (quantization depth up to 16 bits) are used in astronomy and other scientific applications. A very large volume of image data has been taken during operation of a modern project of automatic (i.e. robotic) sky observationsystems. The coder based on the Karhunen-Loeve transform (KLT) has been chosen for astronomical image compression in this paper. The astrometry and photometry measurements have confirmed a possibility of the coder blocks arrangement with production of anaccepted error and a sophisticated data stream.
