Abstract. In sparse signal recovery, hard thresholding algorithms play an important role. By combining hard thresholding techniques with inertial acceleration, the heavy-ball-based hard thresholding algorithm (AIHT) and the heavy-ball-based hard thresholding pursuit algorithm (AHTP) have been proposed in recent years. On this basis, we propose two-step inertial acceleration algorithms AIHT and AHTP for signal recovery. In simulation experiments, we test the performance of AIHT and AHTP in signal recovery and image restoration as examples. The experimental results show that they take less time to recover with the two-step inertial acceleration algorithms, and the recovery effect is improved in some sense.
