Estimation of waves displacement using image analysis

Sub-title

During this semester project, an ImageJ plugin has been developed to measure waves' speed on images. The idea is to detect waves and track them onto the next image. The first step is to select the waves using their darkness (intensity), their size and their position in the image. One must then compute their displacement by measuring the distance between the original wave and the next image.

There is no system to measure waves' speed so the results we obtained cannot be checked. The speed orientation was similar to the wind orientation, though, as we expected. We were also able to find the angle of the camera using the speed measures. This result could be useful in other applications.
