提出了一种结合可逆去隔行的运动JPEG 2000（MJP 2）无损实现技术。可逆去隔行技术是一种能够抑制隔行视频场交错造成的梳齿伪影，并通过逆过程保证原始图像恢复的技术。梳齿伪影影响诸如MJP 2的可缩放的基于帧内的编解码器的性能，并且因此我们已经提出了用于将这种可逆的去隔行作为预滤波器应用于这种可缩放的编解码器的场景，因为可以抑制由于用于低和中等比特率解码的伪影而引起的闪烁，并且可以去除用于高质量解码的滤波效果。在这项工作中，我们进一步提出了一个精确的无损实现技术，通过集成到MJP2编解码器的去隔行和修改适当的标准解码的头信息。仿真结果表明，采用标准MJP2解码器，在低比特率下仍能保持梳齿抑制能力，并且在视频序列“足球”中，与普通场交织相比，该方法的开销小于2.0%。
A lossless implementation technique of Motion JPEG2000 (MJP2) integrated with invertible deinterlacing is presented in this paper. The invertible deinterlacing, which has been previously published, is a technique that suppresses the comb-tooth artifacts caused by field interleaving of interlaced videos and also guarantees the recovery of the original through the inverse process. The comb-tooth artifacts affect the performance of scalable intraframe-based codecs such as MJP2 and, thus we have suggested a scenario for applying this invertible deinterlacing as a prefilter to such a scalable codec since it is possible to suppress flickering due to the artifacts for low and middle bit-rate decoding and to remove the filtering effect for high quality decoding. In this work, we further propose an exact lossless implementation technique by integrating the deinterlacer into MJP2 codecs and modifying the header information for appropriate standard decoding. We demonstrate some simulation results to show that the comb-tooth suppression capability can be kept at low bitrates with standard MJP2 decoders.Furthermore, some experimental results show that the overhead of our proposed method is less than 2.0% compared with normal field interleaving in video sequence 'Football'.
