When applying The result in 2.4.8 was (like it should be): But in 3.2, some memory-corruption happens when src = dst. The result is some memory-garbage.

2017-05-10 10:33:16 -0600 | asked a question | Inconsistent return values on pixel access. Hello Community. I've got that litte snipped here. As you can see, Im accessing the pixel value kind of block-wise and use the columns pixel values as bits for a unsigned int. Block number and unsigned int serve as coordinates for another pixel in another image, set to 255. I've tested everything. After hours of debugging I've found the following: Sometimes the return value of In theses inconsistend cases, the output of the first call for one block is Do I miss something? Have I made an error? Or is there some bogus magic happening thats flipping pixels? Latest OpenCV 2.4 and 3.2 (both causing the same error) is used on an MacBookPro (13", Mid2011) with 4GB RAM and i7. |
