Hello:

I need to be able to apply the Dream Smoothing filter to relatively large image sizes, 100 to 200 megabytes.

Currently it works well on relatively small images, 500 kb to 1000 kb.

I have tried to use the Oil Paint filter in PhotoShop which produces similar effects, but it has similar file size limitations and Adobe won't let me have access to Oil Painter code.

Does anyone know how to get in contact with the filter's author, Arto Huotari? I haven't been able to find his e-mail address on-line.

I need to find someone who knows how to change the filter's algorithm to work with larger file sizes.

I do not have any programming background. I would like to hire someone capable of doing this for me.

Kind regards,
Kent

There is link on the dialog to the right of the filter list in Gmic. just click on it. might need your browser open.:-)
He is also under Naggobot.
And welcome also

By the way. I just run Dream Smoothing on a 90+ MB image and it ran. Does your computer allow large images because it will be bigger after. Mine is now 127 MB

just over 6 hours for huge images I've found. very cool though.

Thank you for your reply to my query.

The image I am working on right now is 230 mb, 10328 pixels x 7760 pixels, about 69" x 52" (175 cm x 132 cm) at 150 pixels per inch.

I am capturing various naturally occurring textures, patterns and colors with an 80 megapixel digital back, then combining and manipulating the images in a series of steps to produce a unique illustration style that will be laser-printed on Canvass. Using a filter that can produce effects like Oil Paint or Dream Smoothing is an important component of this process. I need a minimum of 150 pixels per inch for this output.

Unfortunately the Dream Smoothing filter works well only on relatively small image sizes with diminishing effect as image size increases. I need to have a modified version of the Dream Smoothing filter developed that is capable of applying the effects to large images as well as the existing filter does to small images.

I was able to apply the Dream smoothing filter to images up to about 30 to 50 mb or so with about a 20 to 30 minute wait, but it had very little effect on the image. So even if I could apply the current filter to my much larger images, it would not produce the results I need.

PhotoShop's Oil Paint filter works relatively rapidly on all file sizes, but has the same problem of diminishing effect as file size increases.

As Adobe is no longer supporting the Oil Paint filter (or Pixel Paint) I was hoping they would allow me access to the code for Oil Paint so I could have a developer modify it to work as I need it to on large images. But Adobe has refused my request.

Dream Smoothing is the only filter I have been able to locate that produces effects similar to the Oil Paint filter and, as it is open source, I am hopeful I can have the existing code modified to work as I need it to.

Slight revision of above: I am able to apply the Dream Smoother filter to 100mb images (takes about 15 minutes or so), but the effects the filter produces on images of that size is very slight compared to much smaller image sizes.

I don't see what you expect to see on larger images. As the name implies, this filters smooths things, so it removes detail. If you get it upgraded to work on larger areas, you will lose the finer detail and there is no much purpose using a 80MPix original picture. You would be getting essentially the same result running the filter on a smaller size image and upscaling the result.

I did try upscaling, but I have to bring the image down so drastically in size to apply the amount of effect I need that I lose far too much information when the image is interpolated back up.

I do appreciate your input though.
