Abstract
Optical And Digital Spatial Filtering Of A Simulated Sea Surface
Highlights
The sea surface affected by wind can be considered a random rough surface
During the past hvo decades, efforts to study the behaviour of sea surface waves have been centred on the use of remote sensors
The pixels used for printing the images on the photographic negative were square of size 21 x 21 microns
Summary
During the past hvo decades, efforts to study the behaviour of sea surface waves have been centred on the use of remote sensors. These can be instruments placed on satellites or airplanes La información contenida en una fotografía de una superficie rugosa puede ser procesada por dos métodos. La imagen puede ser digitalizada por un microdensitómetro y el arreglo numérico resultante se procesa con los algoritmos de computación conocidos (Procesado Digital de Imagenes). La imagen fotográfica (negativo) puede ser procesada directamente en un sistema óptico coherente (Alvarez-Borrego y Machado, 1985).
