A method for correcting one or more images of an object (107) from a plurality of images of the object (107), for providing one or more corrected images of the object (107) for further use in a process for generating a representation of the surface of the object, each image of the plurality of images comprising one or more pixels and each pixel comprising a pixel value, wherein one or more illumination sources (104, 105, 106) illuminate the object with different directions of illumination, and each image is associated with a determined direction of illumination, the method comprising the steps of: for each pixel of the plurality of a first image of said plurality of images: a) selecting a pixel in the first image for obtaining the pixel value of the selected pixel; b) selecting at least one corresponding pixel in at least one image of the remaining images of the plurality of images for obtaining the pixel value of the at least one selected corresponding pixel; c) calculating at least one ratio of the pixel value of the selected pixel in the first image to each pixel value of the at least one selected corresponding pixel; d) determining a requirement for pixel value correction of the selected pixel on the basis of the at least one calculated ratio; e) calculating a value (W) based on the at least one calculated ratio to determine a corrected pixel value of the selected pixel; f) replacing the pixel value of the selected pixel with the corrected pixel value in the first image to provide a corrected first image. |
