Abstract
A method for encoding at least one image, including subdividing the image into a plurality of blocks and subdividing at least one current block into a first portion and a second portion. The first portion has a rectangular or square shape and the second portion complements the first portion in the current block. The second portion has a geometric shape with m sides, wherein m>4. Then the first and second portions are encoded.
Claims14
A method comprising:
- coding at least one image by coding device, comprising:
- subdividing the at least one image into a plurality of blocks;
- subdividing at least one current block into a first part and a second part, the first part having a rectangular or square form and the second part forming the complement of the first part in the current block, said second part having a geometrical form with m sides, where m>4;
- and
- coding the first and second parts.
A coding device comprising:
- a non-transitory computer-readable medium comprising instructions stored thereon;
- and
- a processor configured by the instructions to code at least one image by performing acts comprising:
- subdividing the image into a plurality of blocks;
- subdividing at least one current block into a first part and a second part, the first part having a rectangular or square form and the second part forming the complement of the first part in the current block, said second part having a geometrical form with m sides, where m>4;
- and
- coding the first and second parts.
A non-transitory computer-readable medium comprising a computer program stored thereon and comprising instructions for coding at least one image when instructions are run on a computer of a coding device, wherein the instructions configure the coding device to perform acts comprising:
- subdividing the at least one image into a plurality of blocks;
- subdividing at least one current block into a first part and a second part, the first part having a rectangular or square form and the second part forming the complement of the first part in the current block, said second part having a geometrical form with m sides, where m>4;
- and
- coding the first and second parts.
A decoding method comprising:
- decoding a data signal representative of at least one coded image having been subdivided into a plurality of blocks, wherein decoding comprises the following acts performed by a decoding device:
- subdividing at least one current block into a first part and a second part, the first part having a rectangular or square form and the second part forming the complement of the first part in the current block, said second part having a geometrical form with m sides, where m>4;
- and
- decoding the first and second parts.
A decoding device comprising:
- a non-transitory computer-readable medium comprising instructions stored thereon;
- and
- a processor configured by the instructions to decode a data signal representative of at least one coded image having been subdivided into a plurality of blocks, wherein decoding comprises:
- subdividing at least one current block into a first part and a second part, the first part having a rectangular or square form and the second part forming the complement of the first part in the current block, said second part having a geometrical form with m sides, where m>4;
- and
- decoding the first and second parts.
A non-transitory computer-readable medium comprising a computer program stored thereon and comprising instructions for decoding a data signal representative of at least one coded image having been subdivided into a plurality of blocks, when the instructions are run on a computer of a decoding device, wherein the instructions configure the decoding device to perform acts comprising:
- subdividing at least one current block into a first part and a second part, the first part having a rectangular or square form and the second part forming the complement of the first part in the current block, said second part having a geometrical form with m sides, where m>4;
- and
- decoding the first and second parts.
