MULTIPLE COLOR TRANSFER: EXAMPLE-BASED PHOTO ENHANCEMENT

Fig. 1: Here are three sets of examples of why a user might be motivated to use this tool. The left smaller two photos are taken at two different places in one day. The middle two are the same scene taken from different views. The right two are captured a similar object on an airplane and on a mountain peak respectively. The bigger images are results enhanced by using this tool. One of the most common situations in photo editing is that users want some specific effects but don’t know how to achieve them. Nevertheless, they have an image in their mind about how the photo should be, which is derived from a better photo on similar subjects, or from their imagina-tion. With this user motivation in mind, this thesis proposes a method for altering a photo’s color based on the color-ing of another exemplary photo. Users simply set the re-quirement by drawing some pairs of brush strokes in corre-sponding regions and then the tool will perform the editing automatically. 1
