Combination of Frame Differencing and hitTest in as3. Inspired by the Processing sketch of Andy Best where you can pop bubbles if there is movement. By checking the difference between two frames (current and the previous one) we know where there was movement. The movement is stored in a bitmap and with that we can … Read more
QRreader example that uses the QR Code Reader by Logosware (libspark project). Code is improved with Adaptive Threshold (by Quasimondo) and other small modifications to improve the QRcode detection.
