该算法定义了图像区域的相对清晰度判定指标，并根据多焦距图像像素邻域的相对清晰度来逐个选取聚焦清晰的像素点从而构成融合图像。

To overcome this problem, a novel fusion algorithm is proposed, which is based on a new image region focus measure, Relative Activity Level (RAL), presented in this paper.

座位安排是相当有效的(按现代标准，紧凑)，而相对低的(1.2秒)混响时间则保障了良好的语音清晰度。

The seating arrangement is quite efficient (tight by modern standards), and the relatively low (1.2 SEC) reverberation time makes for good intelligibility.

根据指纹的清晰度，汉利认为指纹相对较新，当然不可能来自于50年前，波洛克还活着的时候。

Based on the clarity of the impression, Hanley thought that the fingerprint had to be relatively new-certainly not from half a century ago, when Pollock was alive.
