Command line method for digitizing photos of whiteboards2014 · ▲34
About a month ago, after searching for an existing solution, I built a little script to take photo's of whiteboards and clean them up/make them into near perfect digital representations. Here's the script: #!/bin/bash convert $1 -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 $2 Example Input: Input 1: http://i.imgur.com/CTSIPwm.jpg Input 2: http://i.imgur.com/37GXrwo.jpg Example Output: Output 1: http://i.imgur.com/Qf3jkBW.png Output 2: http://i.imgur.com/oNueb0L.png The…

Eigendrum - Draw any shape and hear what it sounds like as a drum▲243
Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
