对周围相邻的 8 邻居求和（元胞只有两种状态，0 或 1 ）。元胞也有一个单独的状态参量（所谓 记录 ）记录它们之前是否有非零状态的邻居。 在 0 与 1 之间产生一个随机数 r 。 如果总和> 0 （至少一个邻居）并且 r >阈值，或者元胞从未有过一个邻居，则元胞= 1 。 如果总和> 0 则设置"记录"的标志，记录这些元胞有一个非零的邻居。 (8 adjacent neighbors on the surrounding sum (cell only two states, 0 or 1). Cell also has a separate state parameters (so-called ' records' ) record that they have non-zero state before the neighbors. Between 0 and 1 generate a random number r. If the sum of> 0 (at least one neighbor) and r> threshold, or the cell has never had a neighbor, then cell = 1. If the sum> 0 set the " record" sign, record the cell has a non-zero neighbors.)

语音分帧程序，对一个语音信号进行分帧，并研究分帧后的短时能量和过零率特性(Voice framing procedures, a voice signal framing, and to study the sub-frame after the short-term energy and zero crossing rate characteristics)

这个文章说明了格雷算法在心电信号处理上的应用(The paper proposes a learning algorithm for real-time analyzing the gray relations between templates and test electrocardiogram (ECG) signal patterns. Without analyzing relations between the test ECG pattern and every template in the database for the recognition, several training patterns for the learning algorithm are chosen from an ECG waveform database with patient diagnosis information, and then the training result is used to analyze the test ECG.)
