Question

I tried to train eigenfaces using knn. It trained but when I test it with new an image it gives me the error in findnearest function

cv2.error: D:\Build\OpenCV\opencv-3.2.0\modules\ml\src\knearest.cpp:325: error: (-215) test_samples.type() == CV_32F && test_samples.cols == samples.cols in function cv::ml::BruteForceImpl::findNearest

That's my function:

ret,id,neighbours,dist=knn.findNearest(S,cv2.ml.COL_SAMPLE,7)

it looks like your matrix S is not well defined... – fonfonx May 17 '17 at 22:40 — fonfonx, May 17 '17 at 22:40
Thanks fonfonx its working now – Krishna Kamal May 23 '17 at 17:55 — Krishna Kamal, May 23 '17 at 17:55

it is probably an error in the typing of the variable S. I went through an error equal to that and decided to put the test case inside an array and it works to me.

And a didn't use the cv2.ml.COL_SAMPLE, it works with just: knn.findNearest(S, 7) – Thales Carreta Oct 27 '18 at 23:35
