Abstract

Digital image processing is one of the uses of computer technology used to solve problems regarding image processing or imagery so that it is easy to process. The process of applying image processing in this study aims to detect the value analysis of Rupiah coins by applying the Hough Transformation method, with the hough transformation method is expected to detect the nominal of coins because this method is an image transformation technique that can be used to isolate an object in the image by finding its boundaries. From research that has been conducted 10 images of coins on nominal inputs in the form of rupiah coin coins with a nominal value of 100, 200, 500, and 1000 rupiah obtained an accuracy rate of 90%. This means that there are 8 test data that get a true positive (TP) information, meaning that the data is successful, 1 false positive test data (FP) means that the data is not expected because it only gets a nominal result of the etapi coin not being parameterized in the circle of the coin and 1 test data gets a false negative (FN) description, meaning that the test result is wrong in assessing the nominal of the coin due to the image resolution factor that is too small.

Abstract

Currently, many technical term dictionaries that are currently circulating are still in book form, making it difficult for users, especially students, because they have to manually search for the meanings and terms of informatics and the internet. One of the algorithms commonly used in the searching process is the Horspool algorithm. Horspool algorithm is a text matching process. Text matching will run efficiently if you have a table to determine how long the character is shifted if an inconsistency is detected in the jth character of the pattern. So it is hoped that the search process can be made in the application of the informatics and internet term dictionary. By using the Horspool algorithm, word matching will be carried out from the beginning of the text or from left to right so that the number and position of the searched term will determine the duration of the search.
