摘要
The autofocusing technique based on contourlet transform is discussed in this paper and an autofocusing method is proposed for images with much information in certain directions. The experimental results show that the proposed method can focus accurately and the sensitivity ratio is higher than that of the other autofocusing methods based on conventional image

The experimental results show that the proposed method can focus accurately and the sensitivity ratio is higher than that of the other autofocusing methods based on conventional image processing
