中文摘要:
autofocusing 技术在这份报纸基于 contourlet 变换被讨论,一个 autofocusing 方法在某些方向与许多信息为图象被建议。建议方法能精确地集中的试验性的结果表演和敏感比率基于处理 CLC 数字 TN911.73 的常规图象比另外的 autofocusing 方法的高这个工作被中国的国家自然科学基金会支持(资助 No.60472100 , 60672073 ),浙江省的自然科学基础(资助 RC01057 , Y105577 ),中国教育部(资助 No.206059 )的关键工程。
英文摘要:
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 processing
