Abstract: 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.

Abstract translation: 从数字图像信息和与数字图像相关的数字深度信息中提取局部描述符。 本地描述符传达与数字图像相关的外观描述信息和形状描述信息。 基于提取的局部描述符生成一个或多个数字图像的全局表示，并且被散列。 基于散列全局表示生成视觉搜索查询。 视觉搜索查询包括在局部描述符中传达的融合外观描述信息和形状描述信息。 融合可能在生成全局表示之前，散列之前或散列之后发生。
