Space missions currently rely upon wavelet-based techniques for image compression and reconstruction. Recent research has established a methodology for using evolutionary computation to optimize image reconstruction transforms that outperform wavelets under lossy conditions. This paper describes new research that builds upon previous work by evolving matched filter pairs that outperform wavelets and...
Cost-effective storage and timely transmission of medical images are very difficult technical challenges. Compression and reconstruction techniques must guarantee no significant loss of clinical information. This paper presents a convenient technique for improving the quality of reconstructed computed tomography (CT) images previously subjected to specified levels of lossy compression. Our genetic...
Most of the images transmitted from deep space probes to Earth are subject to lossy compression. Recent NASA missions (such as Mars rovers Spirit and Opportunity) have used the ICER progressive wavelet image compressor to achieve state-of-the-art compression performance. The purpose of the research described in this paper was to demonstrate that it is possible to evolve wavelet and scaling numbers...
