The motivation of the project is the analysis of structure-borne sound transmission from floor to ceiling in residential buildings, particularly multi-family houses, using frame-by-frame pixel motion analysis.
First measurements have been documented with help of an instrument metronome set to 160 beats per minute .
Three algorithms of the CV2 python public library have been tested :
- "difference" [cv2.absdiff]
- "optical_flow" [cv2.calcOpticalFlowFarneback]
- "eulerian" [gray + diff * 10]
