This book presents a framework of test methodology to assess spatial domain compression artefacts produced by image and intra-frame coded video codecs. A taxonomy of image and video compression artefacts is presented. This is based on the point of origin of the artefact in the image communication model. This book also presents objective evaluation of distortions known as artefacts due to image and intra-frame coded video compression made using synthetic test patterns. Qualitative definitions of blockiness, blur and ringing artefacts are given. These definitions have been augmented with...
