结果表明：像素点覆盖法所采用的测量尺度是构成图像的最小尺寸——像素点的尺寸。
The results show that the scale of pixel-covering method is pixel that is the least dimension to form images.
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.
