Abstract

The invention discloses an attribute recognition device, method and system and a neural network for recognizing object attributes. The attribute recognition device uses a neural network to recognize an attribute of an object, the neural network including an extraction sub-network, a determination sub-network, and a recognition sub-network composed of at least two recognition branches. The attribute recognition apparatus includes: a unit that extracts a feature from an input image using an extraction sub-network, in which the extracted feature can be used for recognizing an attribute of an object by all recognition branches in the recognition sub-network; a unit that determines at least two identification branches from the identification sub-network based on the input object category by using the determination sub-network; and a unit for recognizing, from the input image, an attribute of an object belonging to the input object category on the basis of the extracted feature, using at least the determined recognition branch. According to the present invention, the model size of the neural network for identifying the attributes of the object is greatly reduced.

Description

technical field [0001] The present invention relates to image processing, and more particularly to, for example, attribute recognition and neural networks for attribute recognition. Background technique [0002] Cameras can be seen everywhere in real life. At this time, performing character attribute recognition (especially, multi-task character attribute recognition) on the character images acquired by the camera is of great significance for monitoring processes such as finding / searching for target people. Among them, the multi-task character attribute recognition means to identify multiple attributes of a person at the same time, these attributes are, for example, the attributes of people's clothing (for example, the type / style / color of clothes, the type / style / color of shoes, whether to wear hat, hat type / style / color, etc.) and / or attributes of the person's appendages (e.g., presence or absence of appendages, bag style / color, manner in which the bag is carried, etc.). Sin...
