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 23):
A method for decoding digital images or video streams, comprising:\n a receiving phase, wherein transformed coefficients (f\u0302) of an encoded portion of an image (f) are received through input means, a rotational phase, wherein at least one rotation angle (\u03b8) is determined, by means of processing means, for rotating basis vectors of a Discrete Cosine Transform matrix (V) in order to inverse transform encoded portion of said image (f), and wherein a rotated transform matrix (V\u2032) is determined by means of the processing means, wherein said rotated transform matrix (V\u2032) can be determined as 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), an inverse transform phase, wherein a reconstructed image (f\u2032) is computed on the basis of the transformed coefficients (f\u0302) and said rotated transform matrix (V\u2032) by inverse transforming said transformed coefficients (f\u0302) from the frequency domain into the space domain by means of said rotated transform matrix (V\u2032), an output phase, wherein the reconstructed image (f\u2032) is outputted through output means.
