Feature Extraction Shape Kawi Numbers and Java Images Using the Zernike Moment

Abstract

The writing of Kawi and Javanese numeric characters has different forms, in order to find out the extraction value of the image form features of Kawi and Javanese numerals, the Moment Zernike method is free from rotation. To prove the Zernike Moment method feature extraction, a number of rare research processes are carried out, the steps are (1) image input, (2) grayscale, (2) threshold and region growing segmentation process, (3) extraction of the Zernike Moment feature. The results obtained from the test from the nearest value approach using city block extraction feature Kawi and Java numeric images with extraction features of rotated features 90° and 180°. The results obtained are the same as 0.01 for the Kawi 1 and 0.02 numbers for Java number 2.
