Method and apparatus for detecting specific external human body parts from texture energy maps of images by performing convolution

摘要

An apparatus for detecting specific human body parts in an image includes: a texture energy analysis unit for analyzing energy distribution in the image and generating texture energy maps; a candidate region-of-interest extraction unit for extracting candidate regions-of-interest for the specific body parts on a given texture energy map by applying a threshold to the given texture energy map, the given texture energy map being selected among the texture energy maps; a candidate mask application unit for performing convolution between candidate masks for the specific body parts and the candidate regions-of-interest and selecting candidate body parts based on results of the convolution; and a body part detection unit for detecting the specific body parts on the image by performing verification on the candidate body parts. The verification is performed by using machine-learning models for the specific body parts.
