ABSTRACT

Noise reduction (denoising) is one important work in seismic data processing. With the reduction of noise we obtain the results expected with S/N (Signal to Noise Ratio) is high. This job is quite challenging, especially if the noise and the signal (in different domains) is not integral, as it is in elementary and junior high diploma blanko. The purpose of this study was to establish the authenticity of diplomas detection model based on elementary and junior high school Image denoising algorithm that gives the user the ease in detecting digital image of the picture on the level of accuracy and speed are significant. Detection method referred to authenticity forms elementary and junior high school diploma is Wavelet Denoising Algorithm Matlab 2013a version that allows for early detection and quickly in order to obtain accurate results validate the authenticity and high quality.
