Sar minimum entropy autofocusing based on prewitt operator

HIGHLIGHTS

• who: Xiaoze Hou and Yanheng Ma from the Army Engineering University, Shijiazhuang, China have published the research: SAR minimum entropy autofocusing based on Prewitt operator, in the Journal: PLOS ONE of August/29,/2022
• what: This paper develops an improved autofocus method based on the Prewitt operator.
• how: This paper proposes a computationally efficient autofocus algorithm combined with image feature points employing the to obtain the image features. Aiming at the above problems this paper proposes a Minimum Entropy Autofocus algorithm based on the Prewitt operator(PMEA). This paper the Prewitt operator is . . .
