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 22):
A method for encoding digital images or video streams, comprising:\n a receiving phase, wherein at least a portion of an image (f) is received by means of 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) for transforming said portion of said image (f), and wherein a 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), a transform phase, wherein transformed coefficients (f\u0302) are computed on the basis of the pixels contained in said portion of the image (f) and said rotated transform matrix (V\u2032) by transforming the pixel values contained in said portion of the image (f) from the space domain into the frequency domain by means of said rotated transform matrix (V\u2032), an output phase, wherein the transformed coefficients (f\u0302) are transmitted to a destination ( 1110 ) by means of output means ( 1105 ).
