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 13):
An apparatus for decoding digital images, comprising:\n input means configured for acquiring at least an encoded portion of at least an image (f) from a communication channel or a storage media (C), output means configured for outputting a reconstructed image (f\u2032), processing means configured for:\n a) receiving, through the input means, transformed coefficients (f\u0302) of said encoded portion of the image (f), \n b) determining at least one rotation angle (\u03b8) for rotating basis vector of a Discrete Cosine Transform matrix (V) in order to inverse transform the received encoded portion of the image (f), \n c) determining a rotated transform matrix (V\u2032) which is the result of a rotation at least one basis vector of said Discrete Cosine Transform matrix (V) by said at least one rotation angle (\u03b8), \n d) computing the reconstructed image (f\u2032) by inverse transforming said transformed coefficients (f\u0302) from the frequency into the space domain by means of said rotated transform matrix (V\u2032), \n e) outputting, through said output means ( 1115 ), the reconstructed image (f\u2032).
