I understand that you wantto postprocess the obtained mask to remove noise and accurately detect the semicircular object in your image. Follow the below steps to achieve that - Mirror your mask about the horizontal axis. Stitch the original and mirrored image horizontally to obtain a complete cir...
2. N x 12(N depends on duration of acquiring of ECG data) 3. I was able to get the frequency spectrum and now I want to remove the noise between 45-55 Hz and then 90-115 Hz. I have applied low pass and band stop filters and All that I have done has made the waveforms with ...
