minimum n. (pl. minimums, -ma ) 最小,最低,最少限度;【数学】极小(值)。 the irreducible minimum 无法减少的最小限度。 The thermometer reached the minimum for the year. 寒暑表降到当年最低度数。 adj. 最少的,最小的,最低的。 the minimum value 【数学】极小值。
A new fisheye image edge extraction algorithm was proposed based on its round valid area ; the overlap area of images to be mosaicked was determinated according to the minimum brightness difference in this area , and thus the fisheye images mosaics were accomplished after images fusion ; finally , the virtual navigation was accomplished through color information extraction form fisheye images directly 摘要根据鱼眼图像的有效区域为圆形,提出了扫描线逼近的轮廓提取算法,基于图像重叠部分亮度差最小的原理,确定了重叠区域,通过对重叠区域进行融合处理实现了鱼眼图像的缝合,最后直接从鱼眼图像上提取颜色信息,重新采样图像数据,实现了基于鱼眼图像的虚拟漫游。
