A method of generating an image signal, the method comprising: receiving a candidate set of images comprising a plurality of images of a scene, at least some images of the candidate set of images being for different view poses of the scene; selecting at least one image of the candidate set of images and initializing a set of included images to include the at least one image; iteratively performing the steps of: generating predicted images for the images of the candidate set of images from the images of the set of included images; determining a prediction quality measure for each image of the set of candidate images, the prediction quality measure for a first image of the set of candidate images being indicative of a difference between the first image and a first predicted image for the first image; selecting a set of selected images from the set of candidate images in response to the prediction qualities, whereby the selected images have the lowest prediction quality measure with respect to the images already included in the set of selected images; for each image of the set of selected images determining a subset of pixels in response to pixel prediction qualities for the pixels of the image; generating a set of partial images corresponding to the set of selected images, the partial image for a given image of the selected set of images comprising only the pixels of the subset of pixels for the given image; including the set of partial images in the set of included images; and removing the set of selected images from the candidate set of images; generating the image signal comprising image data of the images in the set of included images. receiving a candidate set of images comprising a plurality of images of a scene, at least some images of the candidate set of images being for different view poses of the scene; selecting at least one image of the candidate set of images and initializing a set of included images to include the at least one image; iteratively performing the steps of: generating predicted images for the images of the candidate set of images from the images of the set of included images; determining a prediction quality measure for each image of the set of candidate images, the prediction quality measure for a first image of the set of candidate images being indicative of a difference between the first image and a first predicted image for the first image; selecting a set of selected images from the set of candidate images in response to the prediction qualities, whereby the selected images have the lowest prediction quality measure with respect to the images already included in the set of selected images; for each image of the set of selected images determining a subset of pixels in response to pixel prediction qualities for the pixels of the image; generating a set of partial images corresponding to the set of selected images, the partial image for a given image of the selected set of images comprising only the pixels of the subset of pixels for the given image; including the set of partial images in the set of included images; and removing the set of selected images from the candidate set of images; generating the image signal comprising image data of the images in the set of included images. generating predicted images for the images of the candidate set of images from the images of the set of included images; determining a prediction quality measure for each image of the set of candidate images, the prediction quality measure for a first image of the set of candidate images being indicative of a difference between the first image and a first predicted image for the first image; selecting a set of selected images from the set of candidate images in response to the prediction qualities, whereby the selected images have the lowest prediction quality measure with respect to the images already included in the set of selected images; for each image of the set of selected images determining a subset of pixels in response to pixel prediction qualities for the pixels of the image; generating a set of partial images corresponding to the set of selected images, the partial image for a given image of the selected set of images comprising only the pixels of the subset of pixels for the given image; including the set of partial images in the set of included images; and removing the set of selected images from the candidate set of images; generating the image signal comprising image data of the images in the set of included images.
