METHOD AND DEVICE FOR ENCODING ROTATIONAL DATA, CORRESPONDING DECODING METHOD AND DEVICE AND STORAGE MEDIUM CARRYING ENCODED ROTATIONAL DATA

摘要

The invention is made in the field of encoding and decoding of rotational data. In particular, the invention is concerned with encoding and decoding of rotational data for rotational transformation of a template of an object into an instance of the object. When quantizing such rotational data for encoding, precision of the quantized rotational data differently impacts quality of a reproduction. This is compensated by the proposed method which comprises using a processor for executing the steps of determining a size of the instance, and using the determined size for determining a quantization parameter for quantizing said rotational data, using the quantization parameter for quantizing the rotational data, and encoding the quantized rotational data and data referencing the template.
