Abstract:

The contract effort has been toward the development of a data management program for the SDIO Infrared Background Signature Survey, a shuttle-based experiment to be launched in mid 1990, and the super resolution of special data observations of IRAS satellite sensor images of galaxies. The attached report addresses the latter. A new approach to the application of maximum entropy principles in image restoration is being developed. It is an iterative process which combines a Wiener filter restoration and modification to the Weiner image that are Entropy based. The result is an image with well restored frequency content and very little of the spuriousness commonly introduced by inverse filters. The algorithm is fast, stable to convergence, qand will accommodate any specifiable distorting function. Keywords Super resolution Entropy Image restoration.
