Diversity Performance of a Practical Non-Coherent Detect-and-Forward Receiver
—We propose a non-coherent receiver for the fixed detect-and-forward relay channel and derive a closed-form tight upper bound on its bit error probability in Rayleigh fading cha...

Supporting range and segment-based hysteresis thresholding in edge detection
One of the important steps in gradient-based edge detection is thresholding, e.g., hysteresis thresholding in the Canny detector. Traditional approaches use gradient magnitude as ...
