Thus it couldn't be accepted as a mask. After checking for type and shape (has to be uint8 and [rows,cols,1]): print (mask.dtype) print (mask.shape) Convert the mask to gray if it's still 3-channel: WebJan 8, 2013 · In 2004, D.Lowe, University of British Columbia, came up with a new algorithm, Scale Invariant Feature Transform (SIFT) in his paper, Distinctive Image Features from Scale-Invariant Keypoints, which extract keypoints and compute its descriptors.*(This paper is easy to understand and considered to be best material available on SIFT.
