APPARATUS FOR CODING OR DECODING INTRA IMAGE BASED ON LINE INFORMATION OF REFERENCE IMAGE BLOCK |
摘要 |
An apparatus for coding an image is provided to effectively code the image. The apparatus for coding the image includes an input image segmentation unit to segment an input image into a plurality of image blocks including a first image block and a second image block. The apparatus also includes a waveform information generation unit to select a plurality of reference pixels from among pixels included in the first image block, generate first waveform information about the first image block based on a pixel value difference between the selected plurality of reference pixels, and generate second waveform information about the second image block based on a pixel value difference between the pixels included in the second image block. The apparatus also includes a coding unit to code an image included in the second image block based on the first waveform information and the second waveform information. |

1. An apparatus for coding an image, the apparatus comprising:
an input image segmentation unit configured to segment an input image into a plurality of image blocks; a waveform information generation unit configured to select reference pixels of a predetermined direction from pixels neighboring a target image block that is an image block to be coded among the plurality of image blocks, and generate waveform information that represents differences between the selected reference pixels; and a coding unit configured to code an image included in the target image block based on the waveform information. |
