More Information
Summary:This invention includes the following steps: a first overlap cutting step, a first processing step, a first overlap reconstructing step, a second overlap cutting step, a second processing step, and a second overlap reconstructing step. Based on these steps, the single channel data separation is adopted for obtaining the biological information. Only the green channel is considered because it has the lowest influence, followed by the singular spectrum analysis (SSA) process, two times relationship selection process, and the spectral masking process. At last, the final heart rate can be obtained. This invention has the following advantages: (1) its algorithm for extracting human pulse rate of a human face is unique; (2) its application scope is wide; and (3) the single channel separation method can minimize the transmission volume of video data.
