Kanji merupakan salah satu bahasa yang berasal dari negara Jepang. Bahasa Jepang sendiri telah menyebar di berbagai negara terutama di Indonesia. Namum dikarenakan bahasa Jepang bukanlah bahasa yang mudah dipelajari karena bahasa Jepang tidak termasuk kedalam bahasa Internasional. Oleh karena itu diperlukan sistem yang bisa membaca bahasa aksara bahasa Jepang khususnya kanji. Penelitian ini akan difokuskan pada perancangan aplikasi pengenalan karakter optik dari aksara kanji menggunakan ekstraksi fitur chain code untuk melakukan pengenalan pola dari citra aksara kanji dan perhitungan jarak manhattan distance (L1 Metric). Dalam membangun aplikasi digunakan bahasa pemrograman pascal menggunakan Lazarus IDE dan integrasi sistem basis data. Proses dalam penelitian ini terdiri dari 5 tahap yaitu pre-processing, segmentasi, filtering spasial linier, ekstraksi fitur chain code, dan perhitungan jarak nilai fitur. Jarak citra kanji yang diuji akan dibandingkan dengan citra kanji yang sudah dilatih di basis data untuk mencari jarak terkecil. Hasil pengujian yang dilakukan dengan algoritma chain code dan manhattan distance (L1 Metric) menunjukkan bahwa sebesar 21.82% citra tulisan tangan kanji berhasil dikenali dan 78.18% mengalami kegagalan dalam mengenali citra yang diujiUnduhan
