Sobel Operator

Node.js implementation of the Sobel Operator (Sobel-Feldman operator)

  • Edge Detection (sharp changes in contrast)
  • Standard Sobel X/Y kernels
  • Fast (I was able to process 3 million pixels per second on a laptop)

Currently this is only a CLI application, however its code shouldnt be very difficult to implement elsewhere.
