the subject moves, but the camera does not. I don't see that the emissivity of the filter could change the results in this way. These observations are based on a single film clip in which the subject moves their head while breathing. While I can see that the breath would be cooler (avg) than the...
we are indeed seeing extrema at both locations. The breath is measurable as variations against the backgrounds. The problem comes in the explanation for the polarity of the extrema. I expect that the filter would be non-ideal, But I question whether or not we are measuring CO2 at all giving the...
I was hoping that you could help me with a little mystery we're having with an IR Camera. We are using IR to measure respiration and, in hopes of increasing contrast, have installed a bandpass filter to block all but the wavelengths charicteristically blocked by CO2 absorption. When the breath...
