  2. Compression artifact - Wikipedia

    en.wikipedia.org/wiki/Compression_artifact

    As in still image coding, it is possible to apply a deblocking filter to the decoder output as post-processing. In motion-predicted video coding with a closed prediction loop, the encoder uses the decoder output as the prediction reference from which future frames are predicted. To that end, the encoder conceptually integrates a decoder.

  3. Lossless JPEG - Wikipedia

    en.wikipedia.org/wiki/Lossless_JPEG

    The standard Independent JPEG Group libraries cannot encode or decode it, but Ken Murchison of Oceana Matrix Ltd. wrote a patch that extends the IJG library to handle lossless JPEG. [1] Lossless JPEG has some popularity in medical imaging, and is used in DNG and some digital cameras to compress raw images, but otherwise was never widely adopted.

  8. Deblocking filter - Wikipedia

    en.wikipedia.org/wiki/Deblocking_filter

    In contrast with older MPEG-1/2/4 standards, the H.264 deblocking filter is not an optional additional feature in the decoder. [1] [2] It is a feature on both the decoding path and on the encoding path, so that the in-loop effects of the filter are taken into account in reference to macroblocks used for prediction. When a stream is encoded, the ...

    If you've just passed an image challenge, but are immediately prompted by another, there may be an issue with your browser. Before you attempt another image challenge, clear the cache on your web browser. If you're still prompted to retake the image challenge multiple times a day, you might have a more serious issue.
