Abstract: A process and apparatus for applying style images ISj to at least one content image IC containing entity classes i (i: 1, 2, . . . M), wherein attributes of a plurality j of one style images (ISj: IS1, IS2, . . . ISN), each containing entity classes i (i: 1, 2, . . . M), are transferred to the content image IC, the process comprising down-sampling the at least one content image ICi, to derive a content feature vector FCi, down-sampling the j style images ISj, to derive j style feature vectors (FSij: FSi1, FSi2, . . . , FSiN), stylising the content feature vector FCi by transferring attributes of the style feature vectors (FSij: FSi1, FSi2, . . . , FSiN) to the content feature vector FCi, to derive j stylised content feature vectors (FCSij: FCSi1, FCSi2, . . . , FCSiN), combining a blending factor (?ij: ?i1, ?i2, . . . , ?iN) of each of the respective stylised content feature vectors (FCSij: FCSi1, FCSi2, . . .

Abstract: A processing of enhancing the quality of images, wherein a style transfer is performed on a content image using, as a basis, a selected style image. The style image used in the style transfer is selected from a number of candidate style images, each having an associated similarity parameter representative of the degree of similarity with the content image. The selected style image is that candidate style image having a similarity parameter for which the similarity between style image and content image is highest.
