INSTANCE SEGMENTATION METHODS AND APPARATUSES, ELECTRONIC DEVICES, PROGRAMS, AND MEDIA
First Claim
1. An instance segmentation method, comprising:
- performing feature extraction on an image via a neural network to output features at at least two different hierarchies;
extracting region features corresponding to at least one instance candidate region in the image from the features at the at least two different hierarchies, and fusing region features corresponding to a same instance candidate region, to obtain a first fusion feature of each instance candidate region; and
performing instance segmentation based on each first fusion feature, to obtain at least one of an instance segmentation result of a corresponding instance candidate region or an instance segmentation result of the image.

Abstract
An instance segmentation method includes: performing feature extraction on an image via a neural network to output features at at least two different hierarchies; extracting region features corresponding to at least one instance candidate region in the image from the features at the at least two different hierarchies, and fusing region features corresponding to a same instance candidate region, to obtain a first fusion feature of each instance candidate region; and performing instance segmentation based on each first fusion feature, to obtain at least one of an instance segmentation result of the corresponding instance candidate region or an instance segmentation result of the image.

19. An instance segmentation apparatus, comprising:
-
a memory storing processor-executable instructions; and a processor arranged to execute the stored processor-executable instructions to perform operations of; performing feature extraction on an image to output features at at least two different hierarchies; extracting region features corresponding to at least one instance candidate region in the image from the features at the at least two different hierarchies; fusing region features corresponding to a same instance candidate region, to obtain a first fusion feature of each instance candidate region; and performing instance segmentation based on each first fusion feature, to obtain at least one of an instance segmentation result of a corresponding instance candidate region or an instance segmentation result of the image.

20. A non-transitory computer-readable storage medium having stored thereon computer-readable instructions that, when executed by a processor, cause the processor to perform an instance segmentation method, the method comprising:
-
performing feature extraction on an image via a neural network to output features at at least two different hierarchies; extracting region features corresponding to at least one instance candidate region in the image from the features at the at least two different hierarchies, and fusing region features corresponding to a same instance candidate region, to obtain a first fusion feature of each instance candidate region; and performing instance segmentation based on each first fusion feature, to obtain at least one of an instance segmentation result of a corresponding instance candidate region or an instance segmentation result of the image.
