Abstract
3D textured models are an integral part of modern computer graphics. The geometry of these models is represented by a 3D polygonal mesh and the textures by 2D images. 3D textured models occupy more storage space than conventional images, since we need to store both the mesh and the texture. Thus, they can be expensive to store and transmit. One way to reduce these costs is to compress the mesh and texture in 3D models. Compression invariably leads to the loss of visual quality. Therefore, a method for objectively measuring the perceived loss in visual quality is important. There are studies that can mathematically model the perceptual impact of 3D mesh compression. However, there are only a few studies on the perceptual impact of texture compression. In this paper, we perform a subjective experiment to measure the perceived loss of quality of a 3D model caused by JPEG compression of the model’s texture. We propose a simple modeling function that can determine the perceived quality of a 3D model with JPEG compressed texture.
