METHOD FOR VISUAL SEARCH, CORRESPONDING SYSTEM, APPARATUS AND COMPUTER PROGRAM PRODUCT

摘要

Local descriptors are extracted from digital image information and digital depth information related to digital images. The local descriptors convey appearance description information and shape description information related to the digital images. Global representations of the one or more digital images are generated based on the extracted local descriptors, and are hashed. Visual search queries are generated based on the hashed global representations. The visual search queries include fused appearance description information and shape description information conveyed in the local descriptors. The fusing may occur before the global representations are generated, before the hashing or after the hashing.

主权项

1. A method, comprising:
extracting, using digital image processing circuitry, local descriptors from digital image information and digital depth information related to one or more digital images, the local descriptors conveying appearance description information and shape description information related to said one or more digital images; generating, using the digital image processing circuitry, one or more global representations of the one or more digital images based on the extracted local descriptors; hashing, using the digital image processing circuitry, the one or more global representations of the one or more digital images; and generating, using the digital image processing circuitry, one or more visual search queries based on the hashed one or more global representations, wherein the one or more visual search queries include fused appearance description information and shape description information conveyed in the local descriptors.
