It’s the holiday season, and what better way to celebrate than to dig out an old project & massively over-complicate decorating? This is a Christmas tree, with addressable LEDs, where I’ve reconstructed all the 3D positions of every LED & am using that to drive a volumetric effect.
This article presents a machine-learning method for demosaicing images, in which the mosaic itself and the demosaicing network are jointly optimized without any constraints on the mosaic pattern. The system is capable of learning any color filter mosaic, up to and including a unique color filter on every pixel. Code is available on Github: https://github.com/evanfletcher42/DeepMosaic I recently read two papers on […]
This is based on an invited talk I gave this January at IS&T’s Electronic Imaging 2018, in the Photography, Mobile, and Immersive Imaging conference. The slides are uploaded here (PDF, 12MB), but since I tend to put more content in words than bullet points, I’ve also translated the talk into an “article” format in this post. At Occipital, I lead […]
I recently published img2plot, a Python script that generates artistic pen-plotter sketches from arbitrary images. A lot of plotter projects have code for drawing images. Usually they do something with line density and pixel intensities – a semi-random stippling or wave pattern, for example, with smoothly higher density for darker pixels. These can very faithfully represent the image, but they […]
