Discovered today, quite by accident, that Photoshop has a “custom” filter module (Filters > Other > Custom…) – using kernel processing one can make edge detection, blur, and other simple image filters. Above is a directional blur that works similar to an all-over Gaussian blur but in just side-to-side.
For some details and examples, see Ian Albert’s “Custom Filters” post.
After an afternoon of working on a Processing project with Alex Myers, I created a Processing sketch that pixelates and posterizes an image. Next step (and definitely the hardest) will be to find the weighted center of the pixel areas (not each pixel block but areas of the same color). The above image is Van Gogh’s “Starry Night”.
