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.

An age group classification system for gray-scale facial images is proposed in this paper. Four age groups, including babies, young adults, middle-aged adults, and old adults, are used in the classification system.

異步FIFO是用來適配不同時(shí)鐘域之間的相位差和頻率飄移的重要模塊。本文設(shè)計(jì)的異步FIFO采用了格雷（gray）變換技術(shù)和雙端口RAM實(shí)現(xiàn)了不同時(shí)鐘域之間的數(shù)據(jù)無損傳輸。該結(jié)構(gòu)利用了gray變換的特點(diǎn)，使得整個(gè)系統(tǒng)可靠性高和抗干擾能力強(qiáng)，系統(tǒng)可以工作在讀寫時(shí)鐘頻率漂移達(dá)到正負(fù)300PPM的惡劣環(huán)境。并且由于采用了模塊化結(jié)構(gòu)，使得系統(tǒng)具有良好的可擴(kuò)充性。
