WebDecimation consists of the processes of lowpass filtering, followed by downsampling. To implement the filtering part, you can use either FIR or IIR filters. To implement the downsampling part (by a downsampling factor of “M”) simply keep every Mth sample, and throw away the M-1 samples in between. For example, to decimate by 4, keep every ... WebI. Image sub-sampling. The key idea in image sub-sampling is to throw away every other row and column to create a half-size image. When the sampling rate gets too low, we are not able to capture the details in the image anymore.
