Abstract

Problems in image processing to obtain the best smile are strongly influenced by the quality, background, position, and lighting, so it is very necessary to have an analysis by utilizing existing image processing algorithms to get a system that can make the best smile selection, then the Shi-Tomasi Algorithm is used. the algorithm that is commonly used to detect the corners of the smile region in facial images. The Shi-Tomasi angle calculation processes the image effectively from a target image in the edge detection ballistic test, then a corner point check is carried out on the estimation of translational parameters with a recreation test on the translational component to identify the cause of damage to the image, it is necessary to find the edge points to identify objects with remove noise in the image. The results of the test with the shi-Tomasi algorithm were used to detect a good smile from 20 samples of human facial images with each sample having 5 different smile images, with test data totaling 100 smile images, the success of the Shi-Tomasi Algorithm in detecting a good smile reached an accuracy value of 95% using the Confusion Matrix, Precision, Recall and Accuracy Methods.

Abstract

The problem that affects the character segmentation step is the step before character segmentation, namely preprocessing character segmentation or called preprocessing. This poses are strongly influenced by plate lighting conditions, shadows against plates, plate image impurities, plate image resolution, character cutting accuracy, and speed in recognizing characters. In general, identification consists of 3 stages, namely detection, segmentation and recognition. In this study, the use of the otsu method is expected to detect the region on the vehicle license plate, the region in question is the first region to show the regional code, the second region for the registration number and the third region for the sub-region code. In the process, the results of the vehicle number plate detection trial to get a segmentation of 3 regions of the vehicle number plate character did not get the expected results. The results trial obtained the identification of the entire character of the vehicle number plate so that the characters on the vehicle number plate could not be distinguished between the front letter, number, and the back letter. So to maximize the desired results so that getting 3 regions of the otsu method segmentation process needs to be improved using the mathematical morphology method. This mathematical morphology method serves to read the character value of each pixel in the digital image which produces a comparison between the pixels in the image, so morphology techniques are appropriate when used to perform image processing in obtaining the region of the vehicle number plate. From the improvement of the otsu method, the results of the trial were improved. Of the 100 data samples tested, 96 data samples passed and 4 sample data failed, the accuracy value using MSE measurements from the tested data samples received a very high increase, which was 96%.

Abstract

Technological developments rapidly and affect of changes in human lifestyle. The demand of it is increasingly sophisticated technology that cause humans create tools that facilitate human work. One of them is searching location by using GPS (Global Positioning System). It determines the user's location by using Location Based Service. It is expected to overcome the problem of user in searching location. This paper discusses the user searches location by using Location Based Service. Through the help of Location Based Service will be pinned and will help to determine where the location of a user to their android based smartphones. The results can be obtained from the User Acceptance Test (UAT). It has a percentage of 80% of the 20 users performed. Furthermore, it is not appropriate to have a percentage of  20%  of  20 peers. Keywords:Location Based Services, Global  Positioning System (GPS) Android

Abstract

History lessons in Indonesia are taught starting from Elementary School (SD) level. One of materials taught in elementary schools is a national hero figure who has greatly contributed to Indonesian nation. Several images of heroes were immortalized on Indonesian banknotes. The learning method that is carried out only with printed books and lectures tends to make students bored and quickly feel sleepy. In a site like this, interesting learning media is needed. This study seeks to build an android-based application using Augmented Reality technology, using banknotes as markers to produce 3D animation applications that speak about heroes and their historical backgrounds. This application development methodology uses an Incremental model which consists of 4 stages, namely: Analysis, design, code, and testing. Distributed questionnaires get results; Strongly Disagree = 0%, Disagree = 0%, Agree = 43%, and Strongly Agree = 57%. These results indicate that the overall system is running well and feasible to use

Abstract

Pengolahan citra digital adalah suatu disiplin ilmu yang mempelajari hal-hal yang berkaitan dengan perbaikan kualitas gambar (peningkatan kontras, transformasi warna, restorasi citra), transformasi gambar (rotasi, skala, transformasi geometric), pemilihan citra ciri yang optimal untuk tujuan analisis, dan melakukan proses penarikan informasi atau deskripsi objek atau pengenalan objek yang terkandung pada citra. Deteksi tepi merupakan salah satu teknik yang paling sering digunakan dalam pengolahan citra digital. Deteksi tepi juga salah satu langkah prapengolahan yang penting dalam analisis citra. Penelitian ini berpusat pada peningkatan preprosesing menggunakan metode erosi (morphology). Hasil yang telah ditemukan pada penelitian ini menggunakan pengukuran mean sequera error (MSE). Pada penelitian ini akan terlihat perbaikan kualitas citra yang dihasilkan. Dalam sesi pengujian menggunakan matlab 2012, peningkatan terhadap deteksi tepi ini terlihat dengan persentase yang dihasilkan dari 50 data citra yang diujikan dengan tingkat persentase mencapai 96%

Abstract

Madrasah Ibtidaiyah Darussalam is one of the educational institutions in Pekik Nyaring Pondok Kelapa, so that this school has a number of registrants whose number increases every year. The new student admission system used by Madrasah Ibtidaiyah Darussalam still uses excel. In this discussion, the weighting system for new student admissions by applying the Simple Additive Weighting Method (SAW) method uses four criteria, namely by determining the weighting values such as report card score criteria, tahfidz test score criteria, tahsin test score criteria, and academic score criteria. From the calculation results, it is known that A1 = 20.75, A2 = 18.75 and A3 = 20.45 so the SAW method can select alternatives and rank in determining the ranking from the top to the last based on predetermined criteria.
