Method for encoding and decoding an image, and corresponding devices |
| abstract |
A method for encoding at least one block of pixels includes the following steps: ▪ transforming (18) pixel values for said block into a set of coefficients each having a coefficient type; ▪determining, for each coefficient type, an estimated value representative of a ratio between a distortion variation provided by encoding a coefficient having the concerned type and a rate increase resulting from encoding said coefficient; ▪ subjecting coefficients of said set to a quantization step to produce quantized symbols, wherein the subjected coefficients form a subset of said set and wherein the estimated ratios for coefficient types of coefficients in said subset are larger than the highest estimated ratio over coefficient types of coefficients not included in said subset; ▪ encoding (193) the quantized symbol. Corresponding decoding method, encoding and decoding devices are also proposed. |
