Use of two inpainting Techniques to Restore Partially detected Cartographic Features

Abstract

The continuous use of methodologies to extract cartographic features of digital images have been of great importance in the area of cartography. Many techniques can be used by features extraction processes, however, the results obtained by these techniques usually have partially detected features, culminating in loss of quality of the extraction process. To keep searching for better results, it is possible to use techniques based on inpainting, that has as its main purpose image restoration and removal of occlusions. Therefore, the main objective of this article is to show a methodology of reconstruction of partially detected features using two inpainting techniques proposed by [1] and [2], aiming to improve the quality of results in the process of extraction of cartographic features and digital images. Observing the final analysis of the results obtained with the techniques in three entry images, the technique of [1] showed an improvement of 0.61% compared to the extracted feature. While the technique of [2], an improvement of 6.82%. The good results obtained regarding the improvement of the quality of the process of extraction of partially detected cartographic features will be of great use in the area of cartography.
