Intermediary Resolution Explorations

Posted: August 15, 2019 at 4:47 pm

I’m thinking that it makes the most sense to move up in resolution and do some experimentation at each resolution until the desired resolution is reached. It will be clear from this post that the quality of the aesthetic changes significantly at various resolutions. In order to prevent the image from approaching a gradient with such a high number of training iterations (required to provide a good sampling of the underlying diversity of the original painting), I’ve been using very small neighbourhood sizes. The image below is my best choice and it’s trained over 0.5 epochs (half the pixels) and a neighbourhood of 35px. At HD resolution, this image takes 2.5 hours to compute. If you look carefully, you’ll see some dark ‘spires’ growing from the lower left that look to be the same as those I encountered during the development of “As our gaze peers off into the distance, imagination takes over reality…” (2016). I still have no explanation of them…

For comparison, I’ve included the original image and the low resolution sketch below. At the bottom of this post images show the other neighbourhood sizes I experimented with (left: 78px; right: 150px), and rejected due to their over-abstraction.
