PENERAPAN METODE CONTRAST LIMITED ADAPTIVE HISTOGRAM EQUALIZATION (CLAHE) PADA CITRA DIGITAL UNTUK MEMPERBAIKI GAMBAR X-RAY

Abstract

The Contrast Limited Adaptive Histogram Equalization (CLAHE) method aims to reduce noise by
determining the kernel matrix and work by replacing the intensity value of each input image pixel with an
average of the kernel weighting value for each neighboring pixel and pixel itself. In the process of reducing
noise the size of the kernel is very influential in obtaining the results of image quality. The size of the kernel
used by the author in this study is 5 x 5.
This research has produced an application program to reduce noise using the Contrast Limited Adaptive
Histogram Equalization (CLAHE) method. The test x-ray image used in this study uses x-ray images of thorax
scal. The image is inputted and displayed on the program. Then the Contrast Limited Adaptive Histogram
Equalization (CLAHE) process is carried out. Then an image will be produced as desired.
