otsu
OTSU Gray-level image segmentation using Otsu s method.
Iseg = OTSU(I,n) computes a segmented image (Iseg) containing n classes
by means of Otsu s n-thresholding method (Otsu N, A Threshold Selection
Method from Gray-Level Histograms, IEEE Trans. Syst. Man Cybern.
9:62-66 1979). Thresholds are computed to maximize a separability
criterion of the resultant classes in gray levels.
OTSU(I) is equivalent to OTSU(I,2). By default, n=2 and the
corresponding Iseg is therefore a binary image. The pixel values for
Iseg are [0 1] if n=2, [0 0.5 1] if n=3, [0 0.333 0.666 1] if n=4, ...
[Iseg,sep] = OTSU(I,n) returns the value (sep) of the separability
criterion within the range [0 1]. Zero is obtained only with images
having less than n gray level, whereas one (optimal value) is obtained
only with n-valued images.

Discussion-of-raindrop-fall-speed
简单介绍雨滴的形成，运用流体力学相关知识，分析了雨滴下落所受的黏性阻力和压差阻力，考虑雨滴在空气中下落半径增加对雨滴速度的影响，得出了雨滴下落速度和雨滴半径的关系，对雨滴下落的收尾速度进行了一般的讨论。(Brief rain formation, the use of the knowledge of fluid mechanics, analysis of viscous drag and pressure drag the raindrops whereabouts suffered consider raindrops in the air, the whereabouts of the impact of increasing the radius of raindrops speed, to draw raindrops falling speed and raindrops radius the general analysis of the relationship between the terminal velocity of raindrops whereabouts.)
