Actually I want to apply notch filter to remove specific pattern in image just like (line ,circle ,etc..) . I want to remove some specific frequency of line or circle using notch filter or any other way of removing. Can some one guide me how can I remove specific repetitive pattern from image just like circle or line. if you give some example code it help me a lot. because currently I can not understand how I apply filter or notch to remove certain repetitive pattern form Image. Waiting to hear from you soon.
