IMAGE ENHACEMENT PADA CITRA GESTUR TANGAN MENGGUNAKAN CONTRAST LIMITED ADAPTIVE HISTOGRAM EQUALIZATION
نویسندگان
چکیده
Image Enhacement merupakan proses perbaikan kualitas citra yang dilakukan dengan menggunakan beberapa metode. Citra paling sering adalah digital. digital digunakan pada pengolahan biometrik, pengenalan wajah, tanda tangan, bahkan permasalahan Closed Circuit Television (CCTV). Penelitian ini bertujuan untuk memberikan perbedaan hasil image enhacement gambar telah tertangkap oleh CCTV. 3 buah metode yaitu, Histogram Equalization (HE), Adaptive (AHE), dan Contrast Limited (CLAHE) melakukan citra, sedangkan objek akan penelitian gesture tangan. Dari dapat dilihat bahwa Nilai MSE (Mean Squared Error) mendekati angka 0 CLAHE (Contrast Equalization) nilai sebesar 653.5. Untuk PSNR (Peak Signal to Noise Ratio) sendiri besar yaitu 29.9783476895 CLAHE.

متن کاملModulated AIHT Image Contrast Enhancement Algorithm based on Contrast-Limited Adaptive Histogram Equalization
The Adaptive Inverse Hyperbolic Tangent (AIHT) algorithm is capable of enhancing the global contrast of the original image adaptively, while extruding the details of objects simultaneously, cannot enhance local contrast. Therefore, we proposed a ContrastLimited Adaptive Histogram Equalization (CLAHE) modulation based on AIHT contrast enhancement algorithm from conjugate AIHT and CLAHE image con...

Histograms are the basis for numerous spatial domain image processing techniques. Histogram manipulation can be used effectively for image enhancement. In addition to providing image statistics, the information inherent in the histogram is also quiet useful in other image processing applications, such as image compression and segmentation. Histograms are simple in manipulation as well as econom...
متن کاملDetermining Parameters in Contrast Limited Adaptive Histogram Equalization
Contrast Limited Adaptive Histogram Equalization (CLAHE) is an adaptive histogram equalization which was proposed by K. Zuierveld. Block size and clip limit are used to control the quality of results of CLAHE, but have been experimentally determined by users. In this paper, we propose a method to determine two parameters of the CLAHE considering the characteristics of entropy of image. Experime...
