Abstract
A method of decoding feature maps from encoded data. A parameter related to quantisation is determined. According to the parameter, inverse quantisation is performed for samples decoded from the encoded data to decode the feature maps. For at least a part of the samples decoded from the encoded data, one parameter is shared by a group of samples corresponding to a plurality of feature maps.

A method of decoding feature maps from encoded data, the method comprising:
- determining a parameter related to quantisation;
- and
- performing, according to the parameter, inverse quantisation for samples decoded from the encoded data to decode the feature maps, wherein, for at least a part of the samples decoded from the encoded data, one parameter is shared by a group of samples corresponding to a plurality of feature maps.
An apparatus for decoding feature maps from encoded data, the apparatus comprising:
- a determining unit for determining a parameter related to quantisation;
- and
- a quantisation unit for performing, according to the parameter, inverse quantisation for samples decoded from the encoded data to decode the feature maps, wherein, for at least a part of the samples decoded from the encoded data, one parameter is shared by a group of samples corresponding to a plurality of feature maps.
A non-transitory computer-readable storage medium which stores a program for executing a method decoding feature maps from encoded data, the method comprising:
- determining a parameter related to quantisation;
- and
- performing, according to the parameter, inverse quantisation for samples decoded from the encoded data to the feature maps, wherein, for at least a part of the samples decoded from the encoded data, one parameter is shared by a group of samples corresponding to a plurality of feature maps.
A method of encoding feature maps into encoded data, the method comprising:
- determining a parameter related to quantisation;
- and
- performing, according to the parameter, quantisation for samples to be encoded into the encoded data to encode the feature maps, wherein, for at least a part of the samples to be encoded into the encoded data, one parameter is shared by a group of samples corresponding to a plurality of feature maps.
