ABSTRACT
Satellite images provide information on land cover, these will depend on the spatial resolution for analysis, in this
paper we present a technique for image analysis based on edge detection using sobel-based detectors, in their
different shapes. High-resolution satellite images provide a level of detail of land cover in the submetric range, which
is equivalent to detecting objects that measure less than 1 meter on average, which is interpreted in one pixel in the
image; With the analysis of high resolution images, objects such as ships can be determined, which are found in
ports as well as on the high seas. Edge detectors applied to objects present in high resolution images help in the
analysis of the morphology of the object. In the present study, high resolution images corresponding to boats were
analyzed, which allows determining the contour of the boat with respect to sea water. The application of sobel-based
edge detectors and their different shapes allowed determining a greater number of areas that corresponds to the
perimeter of the ship. The results of the present work can be used in pattern recognition techniques to determine the
characteristics of the objects to be analyzed.
