                         depth information of a scene is enabling the deployment of several 
                         applications such as gesture and object recognition and 
                         three-dimensional reconstruction of environments. However, 
                         commercially available sensors output low resolution data, which 
                         may not be suitable when more detailed information is necessary. 
                         With the purpose of increasing data resolution, at the same time 
                         reducing noise and filling the holes in the depth maps, in this 
                         work we propose a method that combines depth fusion and image 
                         reconstruction in a super-resolution framework. By joining 
                         low-resolution intensity images and depth maps in an optimization 
                         process, our methodology creates new images and depth maps of 
                         higher resolution and, at the same time, minimizes issues related 
                         with the absence of information (holes) in the depth map. Our 
                         experiments show that the proposed approach has increased the 
                         resolution of the images and depth maps without significant 
                         spawning of artifacts. Considering three different evaluation 
                         metrics, our methodology outperformed other three techniques 
                         commonly used to increase the resolution of combined images and
