At the expense of increasing the complexity, Zernike Moment (ZM) was used in Crystal Identification (CI) to solve the parallax error with the highest identification performance among recent methods that are based on Digital signal processing (DSP) algorithms. In Positron Emission Tomography (PET) scanners, the CI method must fulfill the real-time event rate processing that requires low complexity and fast algorithms. The main idea of this paper is the complexity reduction of the ZM-based CI…
