Embodiment 1

[0057] Reference manual attached figure 1 -5 shows a method for providing skin moisture analysis of premature infants, including the following steps:

[0058] S100: First, use the frame difference method to track the baby's face area, and then collect the baby's face video through the video acquisition module;

[0059] S101: Obtain the ROI region of the baby in each frame of the video according to the baby's facial video extraction by the image preprocessing module, and identify skin pixels from the pixels in the ROI;

[0060] S1O2: Segment the ROI area of ​​the baby and separate the segmented image into three primary colors to generate an RGB three-channel image, and take the average value of the skin pixels of each channel image, and use the average value as the feature value of the frame image in the corresponding color channel , generating preprocessed digital signals of three channels of green, blue and red;

[0061] S1O3: the preprocessed original signal x R (t),x G ...

Abstract

The invention discloses a premature infant skin moisture analysis method. The premature infant skin moisture analysis method comprises the following steps: performing face tracking on a face region of an infant by adopting an inter-frame difference method to acquire an infant face video; extracting the ROI region of the baby in each frame of picture of the video; the method comprises the following steps: segmenting a baby ROI region, carrying out three-primary-color separation on a segmented image to generate RGB three-channel images, carrying out skin pixel processing on each channel image, and generating preprocessed digital signals of three channels of green, blue B and red; performing standardization processing on the original signal to generate three new signals; performing FFT (Fast Fourier Transform) to obtain a spectrogram, and selecting the maximum peak frequency as a pulse rate estimation value; according to the obtained pulse rate estimation value, carrying out correlation analysis on the basis of taking a green channel signal as a source signal, and obtaining the absolute value of a correlation coefficient, wherein the change of the correlation coefficient is the change of skin moisture. The method and system have huge application potential and has the advantages of being high in heart rate synchronous measurement accuracy, high in noise interference resistance, large in application potential and the like.

Description

technical field [0001] The present disclosure relates to the field of big data technology, in particular to a skin moisture analysis method and system for premature infants. Background technique [0002] Due to the immaturity of the regulation function, premature infants have unstable body fluids and are prone to imbalance. This is the characteristic of his body fluid regulation. Therefore, it is particularly important to do a good job in the regulation and management of water and electrolytes in premature infants. For ultra-low birth weight children, early changes in water and sodium are closely related to physiological weight loss, and they are more prone to water and electrolyte disturbances, which need to be closely monitored. Factors that affect individual needs include daily loss, including overt and non-overt dehydration, dynamic body weight changes, etc. It is especially important to replenish water and electrolytes according to individual needs, and to manage infus...
