Implementasi Metode High Pass Filtering Dan Metode Contras Streching Dalam Perbaikan Kualitas Citra

Abstract

Digital image is an image that can be defined as a function of f (x, y) which has discrete spatial coordinates and brightness levels. However, not all digital images have a visual appearance that satisfies the human eye. Image enhancement is one of the initial processes in image processing (image preprocessing). One of the methods used is contrast stretching and edge sharpening. This Contrast Stretching method can be used to improve the quality of digital images related to lighting, namely by adjusting the brightness and contrast of a digital image, while the High Pass Filtering method is used to clarify the edges of the object.
