1. An apparatus for detecting specific human body parts in an image, the apparatus comprising: 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 using machine-learning models for the specific body parts on the candidate body parts.
