Pulse wave analysis apparatus, pulse wave analysis method, and non-transitory computer-readable storage medium

A pulse wave analysis method executed by a computer, the pulse wave analysis method comprising:

• extracting, from each of a plurality of captured images of a subject, a plurality of image areas corresponding to each of a plurality of parts of the subject respectively, the plurality of parts being not on a same plane and moving together in accordance with the subject's movement, the plurality of parts include three or more parts;
• generating pieces of waveform data corresponding to the plurality of parts based on an image analysis for the plurality of image areas, each of the pieces of waveform data indicating a pulse wave of the subject;
• calculating a first matching degree between the pieces of waveform data;
• calculating a statistical value of a plurality of first matching degrees, the plurality of first matching degrees indicating the matching degree between two or more combinations of two pieces of waveforms data selected from the plurality of waveform data;
• and
• determining whether a noise is included in the pieces of waveform data based on the first matching degree.

A non-transitory computer-readable storage medium storing a program that causes a computer to execute a process, the process comprising:
