Bitrate Ladder Prediction Methods for Adaptive Video Streaming: A Review and Benchmark

no code implementations23 Oct 2023 Ahmed Telili, Wassim Hamidouche, Hadi Amirpour, Sid Ahmed Fezza, Luce Morin, Christian Timmerer

A key component of HAS is the bitrate ladder, which provides the encoding parameters (e. g., bitrate-resolution pairs) to encode the source video.

ConvNeXt-ChARM: ConvNeXt-based Transform for Efficient Neural Image Compression

no code implementations12 Jul 2023 Ahmed Ghorbel, Wassim Hamidouche, Luce Morin

Over the last few years, neural image compression has gained wide attention from research and industry, yielding promising end-to-end deep neural codecs outperforming their conventional counterparts in rate-distortion performance.

AICT: An Adaptive Image Compression Transformer

no code implementations12 Jul 2023 Ahmed Ghorbel, Wassim Hamidouche, Luce Morin

Motivated by the efficiency investigation of the Tranformer-based transform coding framework, namely SwinT-ChARM, we propose to enhance the latter, as first, with a more straightforward yet effective Tranformer-based channel-wise auto-regressive prior model, resulting in an absolute image compression transformer (ICT).
