RuntimeWarning: overflow encountered in ubyte_scalars
You are adding two uint8 values together resulting in an uint8 value. You need to transform your data types in the calculation. I suggest you try this:
pixeldiff = (int(ipxeldiff)+int(currentdiff))/2This should work.
Edit: balanced bracketts
I had a similar problem that I resolved by initializing my numpy arrays as an int64 datatype:
imAnchor = array(Image.open(imList[10]), dtype='int64')
I think your problem stems from this line:
pixeldiff=pixeldiff+currentdiffRemember that pixels are normally saved in uint8 datatype, which is 0 to 255. So if you try to add two of them and it goes over 255, it will fail.
Do something like this:
pixeldiff = (pixeldiff+currentdiff)/2You will still get the relational data, but it will be compressed into the right size of 0-255.
