How to use masking filter to remove particular frequency from an image?
8 views (last 30 days)
I have modified the code of ImageAnalyst for one the tasks that I am currently working on. Goal is to extract the QR code from the image. Previously I extracted the QR code by using a notch filter but it is highly sensitive to distortion and doesnt work as soon as image is no more in-plane.
Attached is the code based on masked filter (originally written by Image Analyst) and the image I am working on. But once I have removed the frequencies, it it gives me a noisy output like salt and pepper noise.
Looking forward to constructive feedback on the query.
