Cover Story：Cui Guangmang, Zhang Keqi, Mao Lei, et al. Micro-image definition evaluation using multi-scale decomposition and gradient absolute value[J]. Opto-Electronic Engineering, 2019, 46(6): 180531.
As an important instrument to observe the micro world, optical microscope has been widely used in medical health, biological detection, industrial production and other related fields. In the process of obtaining micro-image, it is easy to be affected by the noise of imaging link, and the traditional definition evaluation methods often have multiple false peaks, which have their own limitations in the aspects of algorithm sensitivity, unbiasedness and unimodal. The research team of Cui Guangmang, Ningbo Yongxin Optics Co., Ltd. and School of Electronics and Information, Hangzhou Dianzi University, proposed a micro-image sharpness evaluation algorithm by combining the design of multi-scale decomposition tool and gradient absolute value operator, aiming at the quality evaluation of micro-image autofocus and imaging system.
