采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)

Abstract— In the area of image processing, several methods of
edge detection have been proposed till now like Sobel, Robert,
Prewitt, Canny, Marr-Hildreth etc. All these methods are having
their own advantages and disadvantages. In this paper a new
method has been proposed for edge detection using Cellular
Automata. Different rules have been applied for edge detection.
The outputs are better in terms of clarity and computation time.
Finally, the edge detection has been applied for detecting
cancerous cells in brain. Using Cellular Automata rules helps in
determining the exact location and size of tumor as edges
detected using Cellular Automata are fine, continuous and clear.
