Abstract
A bio-index measurement method is disclosed. According to an embodiment, a method of measuring a biometric index of a subject using an artificial neural network in a non-contact manner, performed by one or more processors, may be provided. The method of measuring a biometric index of a subject is performed based on capturing an image of the subject, extracting a plurality of color channel values from the image, and obtaining characteristic values indicating the biometric index based on the plurality of color channel values.
Claims15
A method of measuring a biometric index of a subject using an artificial neural network in a non-contact manner, performed by one or more processors, the method comprising:
- obtaining a plurality of image frames of the subject;
- obtaining a first color channel value, a second color channel value, and a third color channel value for at least one image frame included in the plurality of image frames;
- calculating a first difference value and a second difference value based on the first color channel value, the second color channel value, and the third color channel value for at least one image frame included in the plurality of image frames, wherein the first difference value is a difference value between the first color channel value and the second color channel value for a same image frame, and the second difference value indicates a difference value between the first color channel value and the third color channel value for the same image frame;
- obtaining a first characteristic value based on the first difference value for at least one image frame included in a first image frame group for a first image frame group obtained for a first predetermined time;
- obtaining a second characteristic value based on the second difference value for at least one image frame included in the first image frame group;
- obtaining time series data based on the first characteristic value and the second characteristic value;
- obtaining biosignal characteristic data based on the time series data;
- and
- obtaining a biometric index of the subject using a biometric index obtaining model based on the biosignal characteristic data.
A non-transitory computer-readable storage medium storing instructions thereon, the instructions, when executed by a processor cause the processor to:
- obtaining a plurality of image frames of a subject;
- obtain a first color channel value, a second color channel value, and a third color channel value for at least one image frame included in the plurality of image frames;
- calculate a first difference value and a second difference value based on the first color channel value, the second color channel value, and the third color channel value for at least one image frame included in the plurality of image frames, wherein the first difference value is a difference value between the first color channel value and the second color channel value for a same image frame, and the second difference value indicates a difference value between the first color channel value and the third color channel value for the same image frame;
- obtain a first characteristic value based on the first difference value for at least one image frame included in a first image frame group for a first image frame group obtained for a first predetermined time;
- obtain a second characteristic value based on the second difference value for at least one image frame included in the first image frame group;
- obtain time series data based on the first characteristic value and the second characteristic value;
- obtaining biosignal characteristic data based on the time series data;
- and
- obtain a biometric index of the subject using a biometric index obtaining model based on the biosignal characteristic data.
