Research of Indonesian license plates recognition on moving vehicles

The recognition of the characters in the license plate has been widely studied, but research to recognize the character of the license plate on a moving car is still rarely studied. License plate recognition on a moving car has several difficulties, for example capturing still images on moving images with non-blurred results. In addition, there are also several problems such as environmental disturbances (low lighting levels and heavy rain). In this study, a novel framework for recognizing license plate numbers is proposed that can overcome these problems. The proposed method in this study: detects moving vehicles, judges the existence of moving vehicles, captures moving vehicle images, deblurring images, locates license plates, extracts vertical edges, removes unnecessary edge lines, segments license plate locations, Indonesian license plate cutting character segmenting, character recognition. Experiments were carried out under several conditions: suitable conditions, poor lighting conditions (dawn, evening, and night), and unfavourable weather conditions (heavy rain, moderate rain, and light rain). In the experiment to test the success of the license plate number recognition, it was seen that the proposed method succeeded in recognizing 98.1 % of the total images tested. In unfavorable conditions such as poor lighting or when there are many disturbances such as rain, there is a decrease in the success rate of license plate recognition. Still, the proposed method's experimental results were higher than the method without deblurring by 1.7 %. There is still unsuccessful in recognizing license plates from the whole experiment due to a lot of noise. The noise can occur due to unfavourable environmental conditions such as heavy rain

Improving Cache Hits On Replacment Blocks Using Weighted LRU-LFU Combinations

Block replacement refers to the process of selecting a block of data or a cache line to be evicted or replaced when a new block needs to be brought into a cache or a memory hierarchy. In computer systems, block replacement policies are used in caching mechanisms, such as in CPU caches or disk caches, to determine which blocks are evicted when the cache is full and new data needs to be fetched. The combination of LRU (Least Recently Used) and LFU (Least Frequently Used) in a weighted manner is known as the "LFU2" algorithm. LFU2 is an enhanced caching algorithm that aims to leverage the benefits of both LRU and LFU by considering both recency and frequency of item access. In LFU2, each item in the cache is associated with two counters: the usage counter and the recency counter. The usage counter tracks the frequency of item access, while the recency counter tracks the recency of item access. These counters are used to calculate a combined weight for each item in the cache. Based on the experimental results, the LRU-LFU combination method succeeded in increasing cache hits from 94.8% on LFU and 95.5% on LFU to 96.6%

Template Matching Using Improved Rotations Fourier Transform Method

Template matching is a process to identify and localize a template image on an original image. Several methods are commonly used for template matching, one of which uses the Fourier transform. This study proposes a modification of the method by adding an improved rotation to the Fourier transform. Improved rotation in this study uses increment rotation and three shear methods for the template image rotation process. The three shear rotation method has the advantage of precise and noisefree rotation results, making the template matching process even more accurate. Based on the experimental results, the use of 10°angle increments has increased template matching accuracy. In addition, the use of three shear rotations can improve the accuracy of template matching by 13% without prolonging the processing time

PENGAMANAN DATA MENGGUNAKAN METODA ENKRIPSI EINSTEIN

Dalam proses demokrasi maka semua orang bebas untuk berbicara mengutarakan pendapat dan pandangannya berdasarkan pribadi dan perasaannya, tentu saja dengan melihat bahwa hak demokrasinya tersebut tidak melanggar hak demokrasi orang lain. Kebebasan berkomunikasi ini juga termasuk kebebasan untuk berbicara dengan orang yang diinginkan. Untuk itu akan sangat mengganggu bila isi pembicaraan terutama yang menggunakan teknologi informasi ternyata bocor kepada orang yang tidak berhak dan secara demokrasi ini melanggar haknya, padahal dalam teknologi informasi yang berkembang secara sangat pesat ini ternyata tidak dibarengi dengan penggunaan alat untuk pengamanan data yang tepat dalam sistem informasi. Salah satu teknik pengamanan data informasi di dunia internet adalah penggunaan teknik algoritma kriptografi. Suatu algoritma kriptografi berisi fungsi-fungsi matematika yang digunakan untuk melakukan proses enkripsi dan dekripsi.

Reduction of Kernel Mechanism Processing Time in Multimedia Authoring Tool

Multimedia authoring tools is a tool for designing multimedia documents based on multimedia presentation scenarios designed by the user. Visual media (images, video, animation, text, etc.) and non-visual media (sound, music, etc.) are combined into a multimedia document. A multimedia programming language represents multimedia documents. The core process in multimedia authoring tools is called the kernel mechanism, which consists of two mandatory processes: modeling and verification. Verification carried out consists of time-computation and spatiotemporal verification. The time needed for the verification process on a multimedia authoring tool is highly dependent on the object or media. The relationship between processing time and the amount of media is exponential, so if a lot of media is processed, it will take a very long time. This is the main obstacle of a multimedia authoring tool at this time. The incrementality algorithm can be applied to the verification process in order to reduce processing time to verify multimedia documents. Based on the experimental results, the processing time can be reduced by up to 75%
