Sharpened glimpses of deep space, powered by a pioneering image-deconvolution method.
This book presents the APEX approach to reconstructing fine-scale detail from blurred astronomical images, including Hubble Space Telescope data. It explains how a special class of blurs can be modeled and removed to reveal sharper, more informative pictures of galaxies and other objects.
What you’ll find in this edition:
- A clear overview of how APEX uses Levy-stable blur models to recover hidden detail in gray-scale and color images.
- Practical steps for evaluating image sharpness and preserving total light while stepping the deconvolution back in time.
- Real-world examples from Hubble imagery, including famous galaxy images, to show how sharpening can uncover structural features.
- Guidance on applying the method to different cameras and image formats, with attention to preserving data integrity and avoiding artifacts.
- Understand the concepts behind optical transfer functions and how they relate to image clarity.
- Learn how to judge improvements through visual sharpening and measurable norms.
Ideal for readers of astronomy imaging, science photography, and applied image processing who want a rigorous, accessible look at modern deblurring techniques and their results on real-world data.
