2015-01-05 05:59:29 -0600 | commented answer | OpenCV Error: Assertion failed (!empty()) in detectMultiScale Well, the solution is (for any readers experiencing the same problem): instead of face_cascade.load('haarcascade_frontalface_default.xml') writing the whole path like: face_cascade.load('/home/user/.../haarcascade_frontalface_default.xml') should do it, and you Sir FooBar helped ,me a lot. Thank you very much, here ist your correct answer :) Have a nice day! |
2015-01-05 05:45:30 -0600 | commented answer | OpenCV Error: Assertion failed (!empty()) in detectMultiScale thank you, test = face_cascade.load('haarcascade_frontalface_default.xml') print(test) returns false |
2015-01-05 05:28:55 -0600 | commented answer | OpenCV Error: Assertion failed (!empty()) in detectMultiScale thanks for your fast answer. Since i'm using opencv as a wrapper and the programm is in python, i need a little heads up, how to call the CascadeClassifier::load() from pythoncode!? Thanks in advance |

2015-01-05 05:06:48 -0600 | asked a question | OpenCV Error: Assertion failed (!empty()) in detectMultiScale Hi, i am trying to work with the example from the face-detection tutorial: tutorial link While i do so and try to execute the examplecode in python, the following error occurs: OpenCV Error: Assertion failed (!empty()) in detectMultiScale, file /home/julian/Downloads/opencv-3.0.0-beta/modules/objdetect/src/cascadedetect.cpp, line 1580 Traceback (most recent call last): File "/home/julian/PycharmProjects/PicProcessingTutorial/Face_Detection.py", line 15, in <module> faces = face_cascade.detectMultiScale(gray, 1.3, 5) cv2.error: /home/julian/Downloads/opencv-3.0.0-beta/modules/objdetect/src/cascadedetect.cpp:1580: error: (-215) !empty() in function detectMultiScale What could be the reason for the error, how should i react to fix it? Thank you for your time and advice, regards jla |
