Abstract
A computationally efficient multi-feature image reconstruction algorithm, well adapted for next-generation telescopes, is proposed. This method is more flexible to handle vast amount of visibility data expected in the future. In reconstructing the M87 image with the visibility data simulated on the Low-Frequency Array (LOFAR), this algorithm turns out to be a few hundreds to one thousand times faster and is more resilient to noises than the conventional algorithms.
