The key technology research for the microscopic particles image analysis... Combining with the above methods are tested, and the result shows that, after the background is corrected, we segment the background brightness particle image; the OTSU can obtain ideal image segmentation effect....
Model simulation of unihemispheric sleep.... Raster plot of sleep for left (white) and right (black) hemispheres, with environmental light level indicated by background brightness....
Drift and compensation time course.Top row: background brightness (black dashed) and normalized pupil response across subjects (magenta, mean and s.e.m.)....
Properties of light sources under mesopic vision... The mesopic vision theory is used to study illumination properties of series of light sources, through the test of luminous spectrum and derivation based on the MOVE model, the results show that spectral luminous efficiency function Vmes(λ) is between traditional V(λ) and V′(λ) when the background brightness under mesopic vision condition, and the function of Vmes(λ) is changed with the different of light sources and background brightness....
