| titleOfInvention | Video encoding and decoding method based on three-dimensional discrete cosine transform |
| abstract | FIELD: physics. n SUBSTANCE: adaptation is performed by rearranging fragments of discrete cosine transform (DCT) coefficients obtained after two-dimensional DCT on the time axis and subsequent one-dimensional DCT such that the total number of non-zero transform coefficients after three-dimensional DCT is less than the number of non-zero DCT coefficients obtained after three-dimensional DCT without rearranging two-dimensional DCT fragments. In the disclosed method, after forming a domain measuring n×n×n pixels, DCT coefficients are calculated on spatial coordinates x and y for each fragment of the domain. The fragments are then rearranged in the form of a rearrangement vector and a time DCT operation is performed. The DCT coefficients are sampled, encoded and transmitted over a communication channel with the rearrangement vector. At reception, said procedures are performed in reverse order and the original video stream is restored. n EFFECT: high degree of compression of video data with a given image reconstruction error at reception owing to adaptation to variation of static properties of images. n 3 cl, 9 dwg |
