Abstract:
A method and an apparatus are provided for encoding and/or decoding digital images or video streams. The encoding apparatus includes a processor configured for reading at least a portion of an image (f), determining a rotation angle (θ) on the basis of the portion of the image (f), determining rotated transform matrix (V′) which is the result of a rotation of at least one basis vector of a Discrete Cosine Transform matrix (V) by the rotation angle (θ), computing transformed coefficients (f̂) on the basis of the pixel values contained in the portion of the image (f) and the rotated transform information (V′), outputting the transformed coefficients (f̂) to the destination.

Claim (Index 1):
An apparatus for encoding digital images, comprising:\n input means configured for acquiring at least a portion of at least an image (f) from a source (S), output means configured for outputting at least a portion of an encoded image to a destination, processing means configured for:\n a) reading at least a portion of said image (f), \n b) determining at least one rotation angle (\u03b8) for rotating basis vectors of a Discrete Cosine Transform matrix (V) able to transform said portion of said image (f) into the frequency domain, \n c) determining a rotated transform matrix (V\u2032) which is the result of a rotation of at least one basis vector of said Discrete Cosine Transform matrix (V) by said at least one rotation angle (\u03b8), \n d) computing transformed coefficients (f\u0302) by transforming the pixels values contained in said portion of the image (f) from the space domain to the frequency domain by means of said rotated transform matrix (V\u2032), \n e) outputting, by means of the output means, the transformed coefficients (f\u0302) to said destination.
