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 also.

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

An image size is expressed in pixels, not in bytes of file space, because this depends too much on compression algorithms and actual image
contents.

Since 500k-1MB is the usual disk space size for JPEG images around 4Mpx,
we will assume you are talking about 800Mpx images (25000x25000), 4GB once loaded....

I don't think changing the algorithm is going to help much. What can be
done is cut your image into smaller images of manageable size (with possibly some overlap), apply the filter on each and then blend the results.

Otherwise the GMIC authors hang out on gimpchat.com and on flickr (https://www.flickr.com/groups/gmic/discuss)

Thank you very much for your reply to my query.

Sorry about the incorrect expression for image size. The image I am working on right now is 10328 pixels x 7760 pixels, about 69" x 52" (175 cm x 132 cm) at 150 pixels per inch, 230 mb in uncompressed RAW format.

Unfortunately applying the filter on smaller segments of the image then merging them does not work as it would for a filter that produces an even effect over all. The "flowing" pixel effect this filter produces results in unique patterns for each segment and there is no cohesiveness to the patterns when pieces are reassembled.

I have posted my query on gimpchat.com as well.

Thank you again for your input.
