2013-06-13 02:48:42 -0600 | answered a question | Feature extraction not reproducible Found the root of the problem: I used OpenMP to extract features from multiple images in parallel and to compare them against expected results (which were previously calculated and saved). Hereby, I did not assure the correct order of loading: E.g.: Features from image A were extracted in thread 1 and compared with the expected results of image B (and vice versa). |

2013-05-22 04:04:59 -0600 | asked a question | Feature extraction not reproducible Within a program I've written, I'm reading jpg-images using cv::imread() and extract Sift-features afterwards. I recently updated OpenCV from version 2.4.1 to 2.4.4, but since that day, the feature extraction is not reproducible any more: The number of extracted features, feature locations and descriptors differ when executing my software multiple times (with constant input-parameters, of course) Tests with Surf or Orb result in equal behaviour. |
