Benchmarking image codecs by assessment of coded test images: the development of test images and new objective quality metrics
Amal Punchihewa, Donald G. Bailey, Robert M. Hodgson · Journal of Telecommunications and Information Technology · 2006
Objective quality measures are required for benchmarking codec performance. Our aim was to develop a simple, accurate method capable of rapidly measuring the degree of blockiness, edge-blur and ringing due to image compression. Two test images were designed to emphasise these artefacts. The efficacy of the new metrics is demonstrated using a JPEG codec at a range of compression levels.
