METODE FILTERING CITRA DENGAN MODEL KERNEL 9X9 PIXEL DENGAN SUSUNAN ANGKA-ANGKA PEMBOBOT PADA PERMAINAN SUDOKU

Advance development of Information and Communication Technology nowadays enable the spread of various forms of information including digital image. This is a risk that must be faced, namely the security of information and the validity of the copyright or ownership of a digital image. Masking methods in digital image processing is a technology to keep the information and copyrights on an image. In this study tested various types of 9x9 pixel image to kernel the form of numbers Sudoku. With this filtering method only certain parties who have the right code Sudoku kernel that can restore the image to obtain the actual image information. In this research, has made programs for filtering and restoration. In the examination of cameraman image, error conquered on filtered image with MSE up to 143.0217. Then it restored so that produce a new image with MSE value only 3.6181 which looks like the origin in plain view

Effect of Control Input on the Results of Parameter Identification of Aircraft Conventional Configuration of Longitudinal Flying Dimension

Parameter identification is a process to get real characteristics of the motion dynamics of an object which can then be used to build the dynamics model of the object, which has a very high level of validity and accuracy. The modeling process is usually carried out using aircraft input data and the results of existing navigation data recording. From the data, the model parameters are estimated using the simple least square method. In this study, the simulation was carried out by varying the deflection input in the control field and simulation time. The input given to the longitudinal dimension is the deflection of the elevator control field. The results of parameter identification in the Corsair A-7A plane in the longitudinal dimension indicate that the input form 3-2-1 has a smaller error value than using doublet and pulse inputs. This shows that the input form 3-2-1 is most suitable for the longitudinal dimension among the given inputs
