Downsampling process
WebDownsampling and Aliasing. The downsampling operator selects every sample of a signal : (3.32) The aliasing theorem states that downsampling in time corresponds to aliasing in the frequency domain : (3.33) where the operator is defined as. (3.34) for . The summation terms for are called aliasing components .

WebApr 24, 2024 · The fence-downsampling process is used here which helps to reduce the redundant data in the image. Once the downsampling is done, the fence-downsampled image is processed further by applying the third party compression technique which first divides the image into 8×8 matrices. Then each 8×8 matrix is processed separately. WebThe downsampling process is composed by lowpass filter + decimation. After filtering the input signal, I see that FFT of the input signal and filtered signal are the almost same at the frequencies below the cut-off frequency (that it is good).
