Summary

[edit]
Description
English: This picture shows a comparison of the unprocessed Wide Field/ Planetary Camera (WF/PC) image (A) with images produced by three different image restoration techniques (B, C, D). As discussed in the accompanying background information on image processing, all of these techniques attempt to remove the halos which can be seen around stars in the raw image. The techniques used were: B) Jansson's constrained iterative method (from the Space Telescope Science Institute), C) a constrained least squares/maximum entropy method (from the Goddard High Resolution Spectrograph team), and D) Lucy's iterative method (from the WF/PC team.)
