| titleOfInvention | Encoding method, decoding method and device |
| abstract | An encoding method, a decoding method and device. The encoding method includes: respectively performing ROT forward transformation on the input signals after DCT transformation according to a plurality of groups of preset ROT forward transformation matrixes so as to obtain transformation coefficients after the ROT forward transformation, wherein each coefficient in the ROT forward transformation matrixes can be decomposed into a plurality of shift coefficients, with each shift coefficient being formed of one shift bit and one sign bit; after quantifying the transformation coefficients obtained after the ROT forward transformation, comparing the distortion situations of the output signals calculated according to each group of quantified transformation coefficients; selecting the ROT forward transformation matrix corresponding to the output signal with minimal distortion as the optimal ROT forward transformation matrix of the current encoding block, and encoding according to the optimal ROT forward transformation matrix. In the present application, the multiplication operation in the ROT transformation process is converted to shift operation and addition operations, improving the calculation. |
