COMPARISON OF IMAGE ENHANCEMENT METHODS FOR CHROMOSOME KARYOTYPE IMAGE ENHANCEMENT
Abstract: The chromosome is a
set of DNA structure that carry information about our life. The information can
be obtained through Karyotyping. The process requires a clear image so the
chromosome can be evaluate well. Preprocessing have to be done on chromosome
images that is image enhancement. The process starts with image background
removing. The image will be cleaned background color. The next step is image
enhancement. This paper compares several methods for image enhancement. We
evaluate some method in image enhancement like Histogram Equalization (HE),
Contrast-limiting Adaptive Histogram Equalization (CLAHE), Histogram
Equalization with 3D Block Matching (HE+BM3D), and basic image enhancement,
unsharp masking. We examine and discuss the best method for enhancing
chromosome image. Therefore, to evaluate the methods, the original image was
manipulated by the addition of some noise and blur. Peak Signal-to-noise Ratio
(PSNR) and Structural Similarity Index (SSIM) are used to examine method performance.
The output of enhancement method will be compared with result of Professional
software for karyotyping analysis named Ikaros MetasystemT M . Based on
experimental results, HE+BM3D method gets a stable result on both scenario
noised and blur image.
