而最後的實驗結果中顯示透過 CUDA 運算,演算法得到了將近六倍的加速。 關鍵字:尺度不變特徵轉換、圖形處理器、線性搜尋法、圖書管理、封面辨識 Abstract Many image processing and computer vision technologies are being applied in image information extraction. Among of all, SIFT is extensively applied in plent...
knnMatch方法是K=2的两个特征向量的k-NN匹配(k-nearest neighbors algorithm,K近邻算法),表明每个匹配的前两名作为特征向量返回。之所以我们要的是匹配的前两个而不是只有第一个,是因为我们需要用David Lowe’s ratio来测试假匹配然后做修剪。 之后,用第79行的rawMatches来计算每对描述子,但是这些描述子可能是错误...
Image matching refers to the process of identify homonymy points between two or more images by a certain algorithm. Generally speaking, Image matching technology is of important, not only in the application of image processing technology, but also in the field of pattern information. Besides, it ...
