METHOD AND DEVICE FOR ENCODING IMAGE USING PREPROCESSING |
| 摘要 |
A method of encoding an image includes obtaining a quantization parameter; determining a size of a smoothing block based on the quantization parameter, determining threshold values based on a main pixel in the smoothing block, selecting a pixel having a pixel value between the threshold values, from among pixels included in the smoothing block, performing a smoothing operation with respect to the main pixel based on the pixel value of the selected pixel, and encoding an image with respect to which the smoothing operation is performed. |

1. A method of encoding an image, the method comprising:
obtaining a quantization parameter; determining a size of a smoothing block based on the quantization parameter; determining threshold values based on a main pixel in the smoothing block; selecting a pixel having a pixel value between the threshold values, from among pixels included in the smoothing block; performing a smoothing operation with respect to the main pixel based on the pixel value of the selected pixel; and encoding an image with respect to which the smoothing operation is performed. |
