Compared to the High Efficiency Video Coding (HEVC) standard, VVC offers about 50% compression efficiency gain, in terms of Bjontegaard Delta-Rate (BD-rate), at the cost of about 10x more encoder complexity.

Experiments show that the proposed method can achieve acceleration ranging from 16. 5% to 60. 2% under the RandomAccess Group Of Picture 32 (RAGOP32) configuration with a reasonable efficiency drop ranging from 0. 44% to 4. 59% in terms of BD-rate, which surpasses other state-of-the-art solutions.

State-of-the-art 2D image compression schemes rely on the power of convolutional neural networks (CNNs).

This requires two characteristics: efficient compression of data, to lower the storage cost, and random access ability to extract part of the compressed stream requested by the user (for reducing the transmission rate).

Unlike the H. 265 intra prediction modes, which are each specialized in predicting a specific texture, the proposed PNNS can model a large set of complex textures.

Usually, the rate-distortion performances of image compression are tuned by varying the quantization step size.
