硕士论文 一种基于SIFT的拼接算法 摘要 图像拼接是计算机视觉与图像处理领域的一个研究热点,它是指将同一场景,相互 之间存在部分重叠的图像序列进行空间对准,经图像融合(可能是不同时间、不同视角 或者不同传感器获得)构成一幅无缝包含各图像序列信息、高分辨率或者宽视角的新图 像。图像拼接技术解决了视野与分辨率之间...
(SIFT), is computed from the image to construct a sub-fingerprint. Thanks to the stability of the SIFT feature, the proposed algorithm exhibits a high discrimination and strong robustness. To our knowledge, this is the first algorithm that can simultaneously resist the abovementioned three ...
Late last month, Beijing announced new export control rules restricting the sale of artificial intelligence technology—rules that apparently apply to the algorithm TikTok uses to recommend videos to its users. This means that ByteDance will need the approval of the Chinese authorities—as well as ...
