Extragalactic Foreground Sources… and You!. Benjamin Recchie. The Cosmic Microwave Background. Cosmic Microwave Background (CMB) is an “echo” of the Big Bang. Small anisotropies (less than 1 part in 100000) in CMB can be analyzed to learn about very early universe.By kimama

Foreground subtraction or foreground avoidance?. Adrian Liu, UC Berkeley. Vision. The redshifted 21cm line is possibly our only direct probe of reionization and the dark ages. 21cmFAST, Mesinger et al. Current power spectrum limits from experiments like PAPER….
Foreground/Background In the first photo, the focus is sharp all the way to the horizon far off in the trees. The back of the little girl up front and the sharp focus that goes deep gives a feeling of depth and grandeur of place.
Foreground/Background. Image Segmentation. What is our goal?. To label each pixel in an image as belonging to either the foreground of the scene or the background. Solution?. This problem can be solved efficiently by a minimum cut computation. Likelihood and separation parameters.
Background Middle ground Foreground. An investigation by Nelvin AD 20120522. The space percieved as closest to the viewer. THE BRIDGE: A space to draw inference between the foreground and the background.
