Scalable SSIM Estimation from PSNR for Per-Title and Context-Adaptive Encoding Workflows
Luc Trudeau, Maria G. Martini
Modern streaming pipelines run hundreds of candidate encodes per asset to support per-title encoding, shot-based optimization, and context-adaptive ABR ladder construction. These t…
Estimating SSIM from MSE for DCT-Based Compressed Images via Modeling Local Error Statistics
Luc Trudeau, Maria G. Martini
Efficient and perceptually meaningful quality assessment is a fundamental requirement for image and video processing, compression, and streaming systems. This article shows that, i…
UI-LIC: A Unified Framework for Evaluating Learned Image Compression Models
Nicholas J. Nolen, Luc Trudeau, Andrew C. Freeman
The evaluation and comparison of Learned Image Compression (LIC) systems is complicated by heterogeneous software stacks, varying training conditions, and divergent evaluation meth…
Predicting Chroma from Luma in AV1
Luc N. Trudeau, Nathan E. Egge, David Barr
Chroma from luma (CfL) prediction is a new and promising chroma-only intra predictor that models chroma pixels as a linear function of the coincident reconstructed luma pixels. In…
