weird vertical lines in scan

We got rid of the horizontal lines in the scan. But there seems to be another problem. We see vertical lines now on even perfectly smooth surfaces. I have attached pictures of our scan results.

Hello Ashvi,

which camera are you using? If you are using the Logitech webcam (or similar), there are some issues about the camera settings.

Please see here about resolution:

and here about frame rate:

Hope this helps.

We were able to get rid of those weird vertical grid lines in our scans. We are using a Nikon D90 SLR camera to capture the scan videos. We think that the heavy motion JPEG compression of the D90 and also the jagged downsampling issue caused those vertical grid lines.

We tried the Final Cut plugin to reduce the downsampling artifacts: (see "D90 Upscaler")

After applying the upscaler, the scan result had no more grid lines.
