Title:
心拍数・呼吸数検出装置，方法およびプログラム
Document Type and Number:
Japanese Patent JP5672144
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a heart rate/respiration rate detection apparatus that accurately detects the heart rate and respiration rate from image data including a face.SOLUTION: In the heart rate/respiration rate detection apparatus 1, an optical wavelength component obtaining part 11 obtains RGB components in the image data 2, and a face recognition processing part 12 extracts a face region from the image data 2. An RGB average calculation part 13 calculates an average of the RGB components in the face region, and an independent component analysis part 14 separates components of three independent signals from the average of the RGB components. An independent signal sorting part 15 determines spectrum distribution for each independent signal of the sampled face region, pairs the spectrum distributions of independent signals with high similarity, based on the similarity of waveform of the spectrum distribution, and partitions the spectrum distributions. A heart rate/respiration rate detection part 16 traces the peak frequency of each partitioned spectrum distribution, and estimates the heart rate based on the frequency value of the peak frequency whose positions of appearance converge on a frequency value axis after the lapse of a predetermined time.
