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.

异步FIFO是用来适配不同时钟域之间的相位差和频率飘移的重要模块。本文设计的异步FIFO采用了格雷（GRAY）变换技术和双端口RAM实现了不同时钟域之间的数据无损传输。该结构利用了GRAY变换的特点，使得整个系统可靠性高和抗干扰能力强，系统可以工作在读写时钟频率漂移达到正负300PPM的恶劣环境。并且由于采用了模块化结构，使得系统具有良好的可扩充性。
