US 2019/0102658 A1 · HIERARCHICAL IMAGE CLASSIFICATION METHOD AND SYSTEM

Abstract

A hierarchical image classification method and system are provided. The hierarchical image classification method derives a coarse classification result of an image by analyzing the image according to a coarse classification model, derives at least one fine classification model by inquiring a classification relation table according to the coarse classification result, derives at least one level information by inquiring a level relation table according to the at least one fine classification model, retrieves at least one coarse feature descriptor from the coarse classification model according to the at least one level information, and decides at least one fine classification result according to the at least one fine classification model and the at least one coarse feature descriptor. The hierarchical image classification method may inquire the classification relation table and the level relation table repeatedly to continuously decide other fine classification result(s).
