The 'Greedy' Algorithm Behind Radio Astronomy's Best Images

At the heart of radio astronomy lies a surprisingly simple yet powerful concept: the greedy algorithm. By seeking the most efficient way to explain an image using minimal elements, this technique enables the construction of complex visual data from limited measurements.

While often associated with modern computer vision under the term matching pursuit, its roots trace back to 1974. This inverse modeling approach transforms raw data into the detailed imagery we see today by iteratively refining explanations for the residual error.
