A Comparison of the MEM and Pixon Algorithms for HXT Image Reconstruction
Abstract
Recently a workshop was held in Palo Alto, CA to discuss image reconstruction for the Hard X-ray Telescope (HXT) on the Yohkoh satellite. At the workshop, the participants concluded that a detailed comparison of the primary reconstruction algorithms should be undertaken. We will report on the results of a comparison of the Maximum Entropy and Pixon algorithms using pseudo data. The comparison will check photometric accuracy, speed, and image quality using a number of test images. The test images utilized in the comparison will examine a broad range of reconstruction problems, including the ability of the algorithms to accurately reconstruct single sources, multiple sources and loop-like features, as well as the ability to reconstruct weak sources in the presence of spatially distinct bright sources.
