Intensity gradient based edge detection for pixelated communication systems
The Journal of Engineering, Volume 2019, Issue 12, Page 8463-8470, December 2019., 2019 Pixelated optical communication systems transmit data using a series of encoded pixelated images. The decoding of these pixelated images is important for reliable data communication. This study proposes a novel intensity gradient‐based edge detection (IGED) method for the received pixelated images.
