2019-07-21 05:35:08 -0600 | marked best answer | KNearest Java Assertion Error[SOLVED] I'm still new to OpenCV, but already learned a lot. I am however stuck on the K-NN Algorithm. I'm writing some software to read energy meters and I already succesfully wrote the image processing part. When the processing is finished, I end up with digits like this: For the K-NN part (training and etc), I used almost all code from this OpenCV question. However, when running the following code (and doing the nescessary training in advance): I'm getting this nasty error: I can't seem to find any solution to this.. Anyone got a clue? Thanks in advance! Edit: import as grayscale and resize image added to one_feature in an attempt to solve the error.

2018-06-17 11:45:39 -0600 | marked best answer | Can't get Canny Edge Treshold right I'm trying to extract digits from an analog electricity meter. I have for example following picture: I know that the lightning on this picture isn't equal everywhere, but it's really hard to get this equal due to reflection and etc. When I'm performing Grayscale, Gaussian Blur & Canny Edge on this image, I can't get a decent result. The issue is that I either have to put the Canny Edge treshold too high which causes some digits unreadable or either have to put the Canny Edge treshold too low which causes too much details to be included in the image. Example of too high treshold: Code: Example of too low treshold: Code: Is there any way to perform some kind of 'Adaptive Treshold Canny Edge' on this? Thanks! |
