erik Yes, the artifact it is only produced when using the ImageManip node. About the ImageManip limitations I do not surpass the width of the image (3840 pixels which is also a multiple of 16). I've tried also with the GRAY8 image type and the artifact also appears with this configuration.
I've tested with the following versions of depthai-core:
- 2.17.4
- 2.18.0
- 2.19.1
- 2.20.2
- 2.21.2
The artifact appears in all the versions but for the 2.17.4. In this version the artifact is almost imperceptible, but it does appear when looking carefully (more evident in an image with checkerboard).
To give a little of background, I was working with the 2.17.4 since at that time it was the available release version, so thats it is why I have not notice this artifact. I was intending to update the depthai-core version for a new one to be able to recover the metadata from each image (lensPosition, ISO, exposureTime), and it may be related that from version 2.18.0 to 2.21.2 it is possible to obtain the imaga metada, but the artififact is also more evident for those versions.
