title: Image-quality enhancement of objects in turbid media by use of a combined computational-photonics approach.
abstract: Ultrafast time-gated optical imaging and computational image-enhancement techniques were combined to produce a robust system for viewing objects in turbid media. Image enhancement was implemented by use of images from the early light with a histogram contrast-enhancement algorithm. Image quality was assessed by use of the contrast radius of gyration and the contrast-to-noise ratio. The technique was applied to viewing the dispersion of water droplets emanating from a jet spray and to pictures of an object embedded in turbid media. In all instances there were substantial improvements in image quality at a given time delay.
