The VVV survey (VISTA Variables in the Via Lactea) gives us a great opportunity to study the distribution of galaxies, obscuredby the presence of the Milky Way. This survey includes observations in five near-infrared passbands of the bulge and part of thedisk of the Galaxy. Our work consists in the analysis of the d115 TILE looking for extended objects. We take into account thestar-galaxy separation given by SExtractor and we obtain photometric properties of the extended objects. As a first step, wealso perform a visual inspection of the field. We find 144 extended objects that are considered galaxy candidates. Our main goalis to automatically detect these extended objects and to separate them in a photometric way.
