Abstract
Mesh segmentation (clustering) is a useful tool, which improves compression performance. On the other hand, per-partes processing of meshes often leads to new types of artifacts - cracks and shifts on the borders between clusters. These artifacts are detected by both, Human Visual System (HVS) and perceptually-motivated distortion metrics. In this paper, we present a post processing algorithm, which aims at reducing such artifacts without needing any additional data - using only information about the cluster distribution that is already present at the decoder. A rigid transformation, which minimises the border artifacts, is iteratively computed and applied per cluster. Our experiments show that this approach leads to a reduction of distortion, as measured by the STED metric, by up to 18% for low bitrates. We also present visual results confirming that the improvement is well visible.
