5/10/15/20阶的语音信号LPC 预测及其功率谱，并绘制误差函数图像(5/10/15/20 LPC prediction order of the voice signal and the power spectrum, and the mapping of the image error function)

Implementation of the canny edge detector.

A new concept of tracking ball has been applied of detecting the ball in one frame by finding centroid ball ,finding histogram of the ball region and correlating it with candidate s histogram (by scanning the complete image) in subsequent frames. Matching of histogram indicates presence of ball ,hence tracks it.
