de-projecting pixels of a source image as a colored point cloud, the pixels of said source image comprising a depth attribute and a color attribute, the pixels being de-projected as points having the color attribute of the respective pixel and having a score attributed according to at least one of a local depth gradient and a local color gradient of said respective pixel, wherein a lower gradient resulrs in a higher score; and
projecting said colored point cloud to generate an image and blending the color attributes of the points projected on a same pixel, said blending being weighted by the score of said points.
