back projection

基本解釋

A real-time frame iterative back-projection algorithm for image sequences superresolution is proposed.
提出一種實時幀迭代反向投影算法實現(xiàn)對圖像序列的超分辨率處理。
In the paper, based on the image registration, iterative back-projection technique is used to construct high resolution from image sequences, in which algorithms and realization are given in detail.
文章在圖像配準的基礎之上，采用后向投影迭代算法對圖像序列進行了高分辨率重構，并給出了其中詳細的算法和實現(xiàn)過程。
Results show that the effect of projection noise on the reconstructed fields is represented by a slope function related to the filter used in deflection tomographic filtered back-projection algorithm.
因此提出了改進的偏折層析濾波反投影算法，數(shù)值模擬表明，改進算法在有效抑制傾斜現(xiàn)象的同時，對重建結(jié)果不會造成明顯的失真。

Why seek to replicate back-projection, for instance, when those compelled to use it at the time would have been thrilled to find something more realistic?
NEWYORKER: The Good German
It had to be put together from half a dozen towns, a church from here, a school from there, supplemented with mock-ups, masking mattes, blue- and yellow-screen and back-projection.
ECONOMIST: Robert Boyle
Back to the CBO numbers, the deficit projection for another year of trillion-dollar deficit is based on the idea that the law remain the same now and the Bush-era tax cuts not expire.
WHITEHOUSE: Press Briefing

a method of projecting pictures onto a translucent screen so that they are viewed from the opposite side, used esp in films to create the illusion that the actors in the foreground are moving (Also called background projection)

反投影
Iterative Back Projection(IBP) algorithm is used for super resolution reconstruction of the image sequence.
