CODING OF RESIDUAL DATA IN PREDICTIVE COMPRESSION |
| 摘要 |
Encoding input data includes: generating a first block of coefficients based on a transform performed on a residual block of data for multiple pixels; generating reference information based on a reference block of data corresponding to the residual block of data; and determining losslessly decodable code values representing the first block of coefficients based on the reference information. |

1. A method for encoding input data, the method comprising:
generating a first block of coefficients based on a transform performed on a residual block of data for multiple pixels; generating reference information based on a reference block of data corresponding to the residual block of data; and determining losslessly decodable code values representing the first block of coefficients based on the reference information. |
