摘要
Microscope imaging and focusing technology plays an important role in the image measurement and computer vision. This paper proposes a novel time-domain focusing method. Firstly, edges of original image are detected through gradient operator and local threshold in small window. At the same time, dual-pixel edge effect will be suppressed. Then, the global threshold is used to eliminate the influence of noise. Finally, the normalized curve will be obtained through evaluation function. Experimental results show that the proposed time-domain focusing method can achieve accurate focusing results with effectively suppressing influence of noise, and owns the advantages of single peak and non-bias.
