20150055882 | VEXTEX CORRECTION METHOD AND APPARATUS FOR ROTATED THREE-DIMENSIONAL (3D) COMPONENTS - A 3D model can be modeled using pattern-instance representation, wherein an instance component may be represented as transformation (for example, rotation, translation, and scaling) of a pattern. Quantization errors may be introduced when encoding rotation information, causing different vertex coordinate errors at different vertices of an instance. To efficiently compensate the vertex coordinate errors, an upper bound can be estimated for the vertex coordinate error of a vertex. Based on the upper bound, the codec decides whether the vertex coordinate error of the vertex needs to be compensated, and decides a quantization parameter for compensating the vertex coordinate error if compensation is needed. The upper bound can be estimated at both the encoder and decoder, and thus, no explicit signaling is needed to indicate whether vertex coordinate error compensation is used or to indicate the quantization parameter for the vertex coordinate error. | 02-26-2015 |
20150084953 | METHOD AND APPARATUS FOR ESTIMATING ERROR METRICS FOR MULTI-COMPONENT 3D MODELS - To calculate an error metric between two 3D multi-components models, the facets of 3D components of the first 3D model are uniformly sampled. Between each sampling point in the first 3D model and the surface of the second 3D model, a point-to-surface error is calculated. The point-to-surface errors are then processed to generate the error metric between the first and second 3D models. To speed up computation, the second 3D model can be partitioned into cells, and only the closet cell to a particular sampling point in the first 3D model is used to calculate the point-to-surface error, when computing error or metrics for individual 3D components in the 3D models, the same uniform sampling and cell partition are employed. Consequently, the error of the whole 3D model is substantially a weighted average of the errors computed for the individual components. | 03-26-2015 |
20150084954 | METHOD AND APPARATUS FOR REPETITIVE STRUCTURE DISCOVERY BASED 3D MODEL COMPRESSION - A 3D model can be modeled using “pattern-instance” representation, wherein an instance component may be represented as transformation (for example, rotation, translation, and scaling) of a pattern. To improve compression efficiency, the quantization parameters for the rotation part and translation part for transformation of an instance can be determined based on the quantization parameter used for encoding a corresponding pattern. Specifically, the quantization parameter for the rotation part may depend on the size of the instance, and the quantization parameter for the translation part may depend on the scale of translation. That is, a larger instance may use a finer quantization parameter for the rotation part. The quantization parameters are so determined that quantization errors caused by compressing the patterns, the translation part of transformation, and the rotation part of transformation are at similar levels. | 03-26-2015 |
