OpenCV 4.0.1 pointSetBoundingRect error #5

Closed Erik-Koning closed 5 years ago

Erik-Koning commented 5 years ago

Im augmenting a dataset for object detection in YOLO, using the CLODSA_Plants.ipynb During the the first attempted transformation to do a vertical flip, I am getting an error on the line containing: vFlipImg,vFlipBoxes = vFlipGenerator.transform(img,boxes)

error:

OpenCV(4.0.1-dev) /home/erik/work/opencv/modules/imgproc/src/shapedescr.cpp:741: error: (-215:Assertion failed) npoints >= 0 && (depth == CV_32F || depth == CV_32S) in function 'pointSetBoundingRect'

I have not changed the notebook very much, only changed the paths to my local dataset. Here is a copy of my ipynb CLODSA_Plants_yolo.zip

Hi Erik,

I have uploaded to pip a new version of CLoDSA with support for OpenCV 4.0. You can install it by running !pip install clodsa==1.2.27

It should work properly now. Let me know if you have further problems. Best, Jónathan

Erik-Koning commented 5 years ago

Solved. Thanks!

hi @joheras i use pip2 to install clodsa, it does not work.

joheras commented 5 years ago

Hi @zimenglan-sysu-512 Could you be more specific about the problem? Does pip show an error when you installed Clodsa? Or does the problem arise when using it?

zimenglan-sysu-512 commented 5 years ago

the error as below of using cv2.seamlessClone:

cv2.error: OpenCV(4.1.0) /io/opencv/modules/imgproc/src/shapedescr.cpp:743: error: (-215:Assertion failed) npoints >= 0 && (depth == CV_32F || depth == CV_32S) in function 'pointSetBoundingRect'

It seems that you have not installed correctly OpenCV. You can install the last version using: pip install opencv-python

Or if you want to install a previous version, you can use: pip install opencv-python==3.4.2.16

zimenglan-sysu-512 commented 5 years ago

hi @joheras i try opencv 4.1, 3.3, 3.4.2.16 or 3.4.3.18, it does not work.

joheras commented 5 years ago

Could you send me an example of what you are trying to do to joheras@gmail.com? I can try to reproduce the error and see what it is happening

zimenglan-sysu-512 commented 5 years ago

hi @joheras it's my mistake, that the function seamlessClone need a mask whose values are 255 instead of binary mask. after muliply the binary mask by 255, it fixes the problem. thanks

Great. Let me know if you need further help. Best, Jónathan
