Aiming for low-complexity encoding, distributed video coders still fail to achieve the performance of current industrial standards for video coding. One of most important problems in this area is the accurate modeling of the correlation between the predicted signal and the original video. In our previous work we showed that exploiting the quantization distortion can significantly improve the accuracy...
Distributed video coding allows the compression of video frames in a distributed fashion leading to a rather simple computational encoding, but requiring a complex decoding. The main drawback however is the decoding complexity making some practical applications difficult. Nowadays, most distributed video coding schemes are based on efficient channel codes such as LDPC and Turbo codes. This is the...
In the last few years distributed video coding (DVC) has become a new paradigm for video compression where the encoding process needs to be simple. DVC allows for the development of new applications where the computational complexity and the amount of memory inside the video encoder are limited. In this paper, we introduce a new data representation and coding method for DVC systems. The proposed method...
This paper presents a new distributed video coding (DVC) scheme where the DC and the AC coefficients of DCT transform are separately encoded and transmitted. The DC coefficients are first transmitted to the decoder and compared with their corresponding DC coefficients found in the side information derived within the decoder. The result of the comparison is then transmitted back to the encoder and...
