1. A decoder for decoding a data stream comprising an array of information samples, the decoder comprising:
an extractor configured for:
for a current region of a plurality of regions, which are obtained by dividing an array of information samples:
extracting, from the data stream, a merge indicator,
determining a plurality of candidate regions for the current region, wherein at least one of the plurality of candidate regions has a spatial relationship with the current region within the array of information samples,
based on a determination that a number of regions in the plurality of candidate regions is greater than one and coding parameters associated with the plurality of candidate regions are not identical to each other, extracting a candidate identifier from the data stream, and
identifying a candidate region from the plurality of candidate regions for the current region based on the candidate identifier; and
a reconstructor configured for:
processing the merge indicator to determine copying or computing a first coding parameter associated with the current region based on a second coding parameter associated with the candidate region,
copying or computing the first coding parameter based on the second coding parameter,
and
reconstructing the current region based on the first coding parameter.
