| Subject | downsampling by a fraction |
| From | Mike Sousa <mike_sousa@yahoo.com> |
Hi I need to downsample an image (bitmap image of a Spectrogram) by a fraction, N/D, (rational: ex 4/5). I understand that this can be done with resampling by 4 followed by decimation by 5. If this is true, is there a more efficient way in this case, more efficient == computationally faster)? Thanks...
