    摘要: A composition is disclosed that includes lin− cells that are characterized as expressing CD31, CD34 and CD105, and not expressing c-kit, wherein the composition comprises fewer than 20% of lineage committed cells. Methods are disclosed for isolating CD31+CD34+CD45−CD105+c-kit− cells. Methods for reconstituting hematopoiesis using compositions including CD31+CD34+CD105+CD45−kit− cells are also disclosed.

    摘要: A method and apparatus for the detection of Gaussian noise in a video signal decomposes an image from the video signal to obtain best qualified blocks having a relatively uniform luminance. From the best qualified blocks an average standard deviation is calculated, and then smoothed by temporal filtering. The filtered average standard deviation is finally calibrated against a scale of corresponding input noise levels to obtain the Gaussian noise in the video signal.
