Abstract

This paper presents the results of wave profile detection from video image using Mexican hat function. The Mexican hat function has been extensively used in the filed of signal processing to detect discontinuity in the images. The analysis was done on the numerical image and video images of waves which were taken in the circulating water channel. The results show that Mexican hat function is an excellent tool in the wave profile detection.
