 note = {application, A wave motion on a free surface of the rotating fluid between cylinders which the inner cylinder is rotating and the outer cylinder is stationary was investigated by image processing and analysis. Images taken by a video camera were inputted on a computer and were given a series of image processing. The processed images have the values of the gray level from zero to 255. The frequency of the value of gray level of the image was measured for Reynolds number. Standard deviation on each frequency of the value of the gray level was calculated and was compared for Reynolds number which was changed from zero to 4086. Consequently the wave motions of the free surface were classified the four types.},
