The special construction of human body skin and the theoretical foundation for thering is its optical phenomena triggered to be progress skin image processing, people
Body skin is a translucent body containing sandwich construction, and specific layering of the different researchers to skin has different see
Method.Regard skin as semi-transparent configuration body, be cuticula respectively, epidermis, the skin corium containing artery and venous capillary,
And the hypodermis layer containing fat.Caused optical phenomena is not quite similar between each layer and incident light of skin, different
Absorption of the pigment to light in skin layer is also different.The absorption and reflection of the present embodiment major embodiment epidermis and skin corium to light
Characteristic, this is also the main reason for causing energy of reflection light to change.
Incident ray generates the optical phenomena of complexity during with skin contact.Incident ray reaches the table of skin
During face, about 5% is directly mirrored, and remaining major part will enter the lower surface of skin.Incident light is into epidermis
Afterwards some by melanin absorption, a part is scattered, and the light of remainder will penetrate epidermis enter it is following true
Cortex.And due to the presence of hemochrome, the absorption to light and scattering phenomenon are equally existed in skin corium.Difference
It is that light is to carry out forward scattering mostly in epidermis, so comparatively fairly simple.And enter after skin corium,
Light will produce forward scattering and back scattering, the particularly scattering phenomenon after the upper strata of skin corium-mastoid process layer are more tight
Weight so that portion of incident light is returned in air.Lamina reticularis under skin corium, most of is forward scattering, and light is by one
Removed until penetrating light up to hypodermis and being reflected into outside some is reflected back in air from surface and lower surface, it is remaining
All by the pigment absorption in skin.Although the kind of pigment contained in skin is varied, it is present in the black of epidermis
Absorption of the hemochrome of pigment and skin corium to light is the most obvious, therefore, when melanin in skin and other institutional frameworks not

Pass filter processing, with the influence for adjusting signal waveform and eliminating noise；Heart rate range in view of normal person is 45~240, because
This is respectively 0.75Hz and 4Hz using the upper lower limiting frequency of bandpass filter.Heart rate value modular converter is used for eliminating noise
Three signal sequences to carry out FFT FFT respectively be a kind of DFT highly effective algorithm, referred to as FFT (fast
Fourier transform), the corresponding power spectral density of three signal sequences is calculated, chooses maximum work in G channel signal sequences
Calculated value of the frequency corresponding to rate as heart rate；Three signal sequences after bandpass filtering treatment carry out Fast Fourier Transform (FFT)
To respectively obtain the power spectral density of three signal sequences.The pulse wave signal that G passages in video image include is stronger, therefore
Frequency corresponding to the peak power spectrum of the signal sequence that pixel average is formed in G passage area-of-interests is chosen as heart rate value.
Heart rate is used for describing the technical term of cardiac cycle, refers to the number of heart bounce per minute, is defined by the first sound.Normally into
