Abstract

It has been realized an estimation of variance of the sea surface slopes through the variances on images that consist of bright and dark regions that are called glitter pattern. The probability distribution of the sea surface slopes has been used considering a non-Gaussian case taking in account the skewness and the kurtosis of the sea surface slopes. These relationships of variance have been calculated for five different angles of light incidence on the sea surface and for four different heights of the image sensor. The brightness in the glittern pattern has been modeled using a Gaussian function with information of the incident and reflection light angle in its argument. Some computational aspects and applications for optical engineering are mentioned.
