Representation of a SIFT keypoint.
The keypoint locations are relative to the resampled size in the image pyramid. To get the size relative to the input image, each of (ix,iy,x,y) need to be multiplied with 2^o, where o is the octave index of the keypoint. The octave index is -1 for the upsampled image, 0 for the input image and >0 for subsampled images. Note that the scale of the KP is already relative to the input image.
