Removing Black Borders

Post by jpv1960 »

Firstly, can I just say XnConvert and XnView are fantastic packages.

I am a new member.

I have made a machine to scan 8mm cine films that my dad took in the 70s.

I was wondering if XnConvert can remove the black border from each photo. The only problem with using the 'crop' option is that it removes a fixed amount, which is no good as the size of the border changes slightly on some photos.

I have tried all other options but no joy. I thought Automatic crop with colour selection would sort the borders, but I must be doing something wrong.

I could do it manually with XnView - 'Crop/Save/Next' option which is great but it would take me many years!

I attach two pictures, (they are out of focus, but ignore that as it was only a test).
I have reduced them in size by a huge amount for upload here.

It would take some quite sophisticated software to do what you really want, I think... :wink:

I don't know whether Adobe Photoshop could do it, probably not, or whether someone has developed some special software for that sort of task??

The Autocrop action is in my experience a difficult function to use, and as the algorithm used isn't very sophisticated, there are certainly limits on the results that can be achieved even in fairly favourable situations.

If you have to compromise and accept a partial improvement, as some areas to be removed are common to all images, the Crop action should enable you to do that, depending on the extent to which you are prepared to accept cropping slightly inside some images to avoid a thin black border.

I will have another look at Adobe Photoshop, I have the full CS6 version, which is quite old now.

I can check out the image stabilizer in Adobe premier pro, Final Cut and DaVinci Resolve once I have converted the images into a movie.
