Content-Driven Frame-Level Bit Prediction for Rate Control in Versatile Video Coding
Amritha Premkumar, Prajit T Rajendran, Vignesh V Menon +1
Rate control allocates bits efficiently across frames to meet a target bitrate while maintaining quality. Conventional two-pass rate control (2pRC) in Versatile Video Coding (VVC)…
Adaptive Resolution and Chroma Subsampling for Energy-Efficient Video Coding
Amritha Premkumar, Christian Herglotz
Conventional video encoders typically employ a fixed chroma subsampling format, such as YUV420, which may not optimally reflect variations in chroma detail across different types o…
Fast Multirate Encoding for 360° Video in OMAF Streaming Workflows
Amritha Premkumar, Christian Herglotz
Preparing high-quality 360-degree video for HTTP Adaptive Streaming requires encoding each sequence into multiple representations spanning different resolutions and quantization pa…
ICME 2025 Generalizable HDR and SDR Video Quality Measurement Grand Challenge
Yixu Chen, Bowen Chen, Hai Wei +16
This paper reports IEEE International Conference on Multimedia \& Expo (ICME) 2025 Grand Challenge on Generalizable HDR and SDR Video Quality Measurement. With the rapid developmen…
Learning Quality from Complexity and Structure: A Feature-Fused XGBoost Model for Video Quality Assessment
Amritha Premkumar, Prajit T Rajendran, Vignesh V Menon
This paper presents a novel approach for reduced-reference video quality assessment (VQA), developed as part of the recent VQA Grand Challenge. Our method leverages low-level compl…
Quality-Aware Dynamic Resolution Adaptation Framework for Adaptive Video Streaming
Amritha Premkumar, Prajit T Rajendran, Vignesh V Menon +3
Traditional per-title encoding schemes aim to optimize encoding resolutions to deliver the highest perceptual quality for each representation. XPSNR is observed to correlate better…
Video Super-Resolution for Optimized Bitrate and Green Online Streaming
Vignesh V Menon, Prajit T Rajendran, Amritha Premkumar +2
Conventional per-title encoding schemes strive to optimize encoding resolutions to deliver the utmost perceptual quality for each bitrate ladder representation. Nevertheless, maint…
Energy-efficient Adaptive Video Streaming with Latency-Aware Dynamic Resolution Encoding
Vignesh V Menon, Amritha Premkumar, Prajit T Rajendran +4
Traditional per-title encoding schemes aim to optimize encoding resolutions to deliver the highest perceptual quality for each representation. However, keeping the encoding time wi…
