DIGITAL IMAGE PROCESSING METODE MEDIAN FILTERING DAN MORFOLOGI OPENING DALAM REDUKSI NOISE CITRA

Abstract

- Technological advances called scanners or scanning tools can convert documents into digital images by scanning. Apart from that, the scanning process can also be carried out using a good-quality camera. Digital data can be stored and viewed again quickly, so the scanning process has problems. This lies in the difference in paper quality, making the scan results look bad or much noise, making the image unclear. Noise is a disturbance in the image in the form of spots in the picture, usually caused by imperfections in the scanning process or dirt in the document. Thus, two methods are used, namely Median Filtering and Opening Morphology.
