摘要：
An apparatus and method based on image for detecting heart rate activity is provided. The method includes: obtaining a plurality of color images based on a complexion target condition, defining a target region performing color composition analysis on the target region to obtain red channel signal, green channel signal and blue channel signal, respectively performing independent component analysis on separate red, green and blue channel signals to obtain separate first independent component signal, second independent component signal and third independent component signal performing frequency domain transform, signal energy computation and signal optimization processes on separate first, second and third independent composition signals to obtain a filter signal, comparing filter signal based on a pre-set condition to determine if target region belonging to a human and performing a bio-physiological information analysis.本揭露是關於一種影像式心率活動偵測裝置與方法,該方法包含以下步驟:針對一監測對象取得複數彩色影像;根據一預設之膚色目標條件,界定彩色影像中之一目標區域;針對目標區域執行一彩色影像組成分析,以取得一紅色頻道訊號、一綠色頻道訊號以及一藍色頻道訊號;依據一獨立成分分析法針對紅色、綠色以及藍色頻道訊號進行運算,以分別取得第一、第二以及第三獨立成分訊號;針對第一、第二以及第三獨立成分訊號分別執行一頻域轉換程序、一訊號能量運算程序與一訊號適化程序,以取得一濾波訊號;並根據一預設條件針對濾波訊號執行比對,以確認監測對象是否為真人,並據之作出一分析指示;以及根據該分析指示執行一生理資訊分析程序。S301‧‧‧取得彩色影像S302‧‧‧目標區域偵測S303‧‧‧影像成分計量分析S304‧‧‧獨立成分分析S305‧‧‧真人辨識判定S306‧‧‧生理資訊分析S307‧‧‧輸出資訊
