Monitoring of objects based on frequency spectrum of motion and frequency filtering

A monitoring system, comprising:

• an imaging device that records a scene containing at least one machine and having a plurality of components;
• a processor operably connected with the imaging device and executing software which is configured to:
• obtain a video recording, consisting of a plurality of video frames, of the machine in motion;
• obtain from the video recording a frequency spectrum of motion present in the video recording;
• select at least one frequency or at least one frequency range depicted in the frequency spectrum which is associated with motion in the video recording occurring at the at least one frequency or the at least one frequency range;
• construct one or more filters associated with the at least one frequency or the at least one frequency range;
• apply the one or more filters to enhance, remove or isolate motion in the video recording occurring at the at least one frequency or the at least one frequency range selected;
• and
• produce one or more new video outputs which create a visual presentation of a subset of the motion of the machine in the video recording.

A method for monitoring a machine, comprising:

• obtaining a first video recording comprising a first set of video frames of the machine in motion;
• obtaining from the first video recording a first frequency spectrum of motion present in the first video recording;
• selecting at least one frequency or at least one frequency range depicted in the first frequency spectrum which is associated with motion in the first video recording occurring at the at least one frequency or the at least one frequency range;
• constructing one or more filters associated with the at least one frequency or the at least one frequency range;
• and
• applying the one or more filters to enhance, remove or isolate motion in the first video recording occurring at the at least one frequency or the at least one frequency range selected;
• storing said one or more filters;
• obtaining a second video recording comprising a second set of video frames of the machine in motion;
• and
• applying to a second frequency spectrum obtained from the second video recording at least one of said stored filters that was applied to the first frequency spectrum, thereby producing one or more new video outputs which create a visual presentation of a subset of the motion of the machine in the second video recording.
