Color Image Enhancement using Contrast Stretching on a Mobile Device

Low quality digital images are still a common problem to all of us. It happens under low lighting condition, interference of atmospheric veil and other conditions. Automated enhancement on a mobile device is still a challenge. This research introduced and implemented an enhancement tool using contrast stretching method. Pixels are stretched within the non-outlier range from the input image. Higher quality images with less noise were produced. This tool is embedded into a mobile device, namely Beagleboard-XM on a Linux environment.
