Hi all, I’m planning on creating a stereo camera that will have two camera modules on flexes. They will have different Z-offsets from each other, but will otherwise be pointed in the same direction (co-planar). Will I … --- ## [Bad conversion to jpg from 16UC1 image or jpg compression artifacts?](https://forum.opencv.org/t/bad-conversion-to-jpg-from-16uc1-image-or-jpg-compression-artifacts/20737)
