Here we can see the results of two methods applied to the same image shown on the monitor simultaneously. The split screen feature will be available in version 2.5 of the Imaging Whiteboard.
Noise is added to the image and the set memory control will write the noisy image to the secondary memory. The temporal filter is applied to the primary memory. Swap memory switches the primary and secondary memories. The 3×3 median filter is applied. The monitor shows the primary image (morphology result) on the left, and the secondary (temporal filter) on the right.
White noise will contain all frequencies. By applying filters to white noise and viewing the resulting spectrum the effects can be viewed. Here we see the test signal generator producing white noise on 2 channels and the resulting spectrum. The high pass filter is applied to the signal and the resulting spectrum with low frequencies eliminated is shown. The low pass filter is then applied eliminating the high frequencies.
