Gaussian Pulse Based Tone Reservation for Reducing PAPR of OFDM Signals
Abstract – One of the major drawbacks of OFDM is high Peakto-Average Power Ratio (PAPR) which can result in poor power efficiency and serious distortion in the transmitter amplif...

The "dead reckoning" signed distance transform
Consider a binary image containing one or more objects. A signed distance transform assigns to each pixel (voxel, etc.), both inside and outside of any objects, the minimum distan...
