Abstract
A recognition apparatus for extracting first features of an object from a region of the object; obtaining second features of the object at least based on confidence information for first attribute of the object; determining sample information from pre-determined sample information based on the obtained second features; and recognizing the first attribute of the object based on the determined sample information.
Claims10
A recognition apparatus, comprising:
- one or more processors;
- and
- at least one memory coupled to the one or more processors, the at least one memory having stored thereon instructions which, when executed by the one or more processors, cause the apparatus to:
- extract image features of an object from a region of the object which is obtained from an image;
- obtain confidence information for a first attribute of the object based on the extracted image features and a classifier for the first attribute;
- obtain a second feature by merging a plurality of obtained confidence information that the object belongs to each value or class for each attribute;
- determine sample information by matching the second feature with a confidence information contained in pre-determined sample information, wherein the pre-determined sample information contains the confidence information of the first attribute and Ground Truth (GT) of the first attribute for each registered image;
- and
- recognize, based on a GT contained in the determined sample information, the first attribute of the object included in the image.
