Reduction of I-pulsing artifacts
Various methods and systems are provided for reduction of I-pulsing artifacts. In one example, a portion of a picture is modified to be encoded as an I picture based in part upon a picture that precedes the picture. The modification can reduce an I-pulsing artifact associated with the I picture. The modified picture is intra-coded for inclusion in a series of encoded pictures, which may then be transmitted. In another example, an encoder includes adaptive pre-processing circuitry and intra-encoding processing circuitry. The pre-processing circuitry modifies a portion of a first picture based in part upon a second picture that precedes the first picture in a series of video pictures. For example, the modification may be based upon coding noise associated with the preceding picture. The intra-encoding processing circuitry encodes the modified picture as an I picture.
