摘要: | Object scalability is a new trend in video coding research. This paper presents an attempt of designing an object-oriented coding based on the notion of irregular mesh and image warping. Three techniques are employed: motion compensation based on image warping, image segmentation and object tracking based on (mesh) nodal point adjustment, and nonrectangular DCT coding performed on the irregular mesh. The preliminary simulation results of the PSNR values and the subjective coded image quality indicate that this coding scheme is suitable for object scalable coding at low bit rates. |
