I need to use the scale-space representation of my input image for post-processing purposes, but am unsure if it is possible to extract it in any way? I'm using the KAZE module for computing keypoints and descriptors, and in doing this a scale-space is constructed for my input image mid process anyway, so I thought if there's a simple way of using that that would be really great for my use-case.
Thanks for the help,

If
The first point is **P1 [x1,x2,...,xn]**
The second point is **P2 [y1,y2,...,yn]**
so ，the Euclidean space distance from P1 to P2 is
**d(P1,P2) = sqrt ( (x1-y1)^2 + (x2-y2)^2 + ... + (xn-yn)^2 )**
so , in the face recognition field , for example , in many open source ，
every point have x coordinate value and y coordinate value ,
I think it is ,
The first face is **P1 [(x1,y1),(x2,y2),...,(xn,yn)]**
The second face is **P2 [(a1,b1),(a2,b2),...,(an,bn)]**
so ，the Euclidean space distance from P1 to P2 is ________________________________ ?
the result is too complex , even is unsolvable .
I don't know if I have a problem with my understanding ?strivingMon, 04 Dec 2017 22:01:04 -0600http://answers.opencv.org/question/179732/OpenCV, Space Time Interest Points (STIP) & Camera Motionhttp://answers.opencv.org/question/91421/opencv-space-time-interest-points-stip-camera-motion/ I understand the implementation of space(spatial) time(temporal) interest points by Laptev http://www.di.ens.fr/~laptev/download.html#stip required OpenCV but since the release of the updated STIP code in 2011 has OpenCV integrated the feature into its toolkit or does OpenCV have its own similar function and how susceptible are STIP methods to camera motion mobmscWed, 30 Mar 2016 14:40:32 -0500http://answers.opencv.org/question/91421/Can anybody tel me how to create a n-dimensional spacehttp://answers.opencv.org/question/12475/can-anybody-tel-me-how-to-create-a-n-dimensional-space/I have 10 activities 435 features and 100 samples for each activity. so now, i need to create a 435-dimensional feature space to place these features for 100 samples of 10 activities.
