Abstract
The present invention generally relates to COLOR transfer between two images. COLOR transfer is a known technic consisting in modifying the COLORs of a source image by applying the COLOR palette of an example image without changing the source image structure. A lot of COLOR transfer method are known which consist in transferring COLORs between two images, however, those methods do not preserve the quality of the bokeh in areas of an images that are not in focus at a given depth. This results in a navigation in the depth dimension that is not smooth. It is proposed to modify the COLORs of a focal stack of a scene according to a COLOR palette by propagating the COLORs of the pixels in focus in different layers of the reCOLORed focal stack to the layers of the reCOLORed focal stack located behind the layer wherein a considered pixel is in focus.
