Encoding/Decoding Processing Method and Apparatus for Image Segmentation Manner

A decoding processing method for an image segmentation manner, comprising:

• decoding encoding information of a segmentation manner of an image block in a depth modeling mode 1 (DMM1) decoding process, to obtain a decoding value;
• obtaining an initial value corresponding to a size of the image block, wherein value=k−2a-x, where x is a quantity of bits that need to be saved, k is a quantity of all segmentation manners corresponding to the size of the image block, and a is a quantity of bits required for representing all the segmentation manners;
• and
• obtaining, according to the decoding value and the initial value a serial number value of the segmentation manner used for the image block.

An encoding processing apparatus for an image segmentation manner, comprising:

• a non-transitory computer readable medium having instructions stored thereon;
• and
• a computer processor coupled to the non-transitory computer readable medium and configured to execute the instructions to:
• obtain a size of a to-be-encoded image block and a serial number value of a used segmentation manner in a depth modeling mode 1 (DMM1) encoding process;
• obtain an initial value corresponding to the size of the image block;
• obtain, through calculation, an absolute value of a difference between the initial value and the serial number value of the segmentation manner, wherein value=k−2′, where x is a quantity of bits that need to be saved, k is a quantity of all segmentation manners corresponding to the size of the image block, and a is a quantity of bits required for representing all the segmentation manners;
• and
• encode the absolute value using a-x bits, to obtain encoding information of the segmentation manner of the image block.
