TOOLS PENGOLAHAN CITRA

Python adalah bahasa pemrograman open source. Dibuat oleh Guido van Rossum dan rilis pertama kali pada 1991

​

Python terkenal karena kemudahan dalam penggunaan dan tersedianya banyak library.

​

Library adalah kumpulan program/fungsi yang bisa digunakan oleh pemrogram. Sehingga pemrogram tidak perlu lagi membuat “codingan” dari nol.

Penjelasan script adalah sebagai berikut :

•import cv2

import adalah perintah untuk memanggil library. Dalam hal ini karena library yang dipanggil adalah openCV maka dilakukan import cv2. cv2 adalah kode untuk openCV.

​

•image

image disini merupakan variable. Variable ini diisi dengan file citra butterfly.png. File ini bisa diganti dengan file citra yang dimiliki. Akan tetapi harus satu folder dengan file .py ini. Selanjutnya untuk memanggil file ini digunakan perintah cv2.imread

Perintah ini digunakan untuk menampilkan citra butterfly.png yang sudah ditampung di variable image. Sintaks “Contoh” hanya untuk memberi judul saja.

​

•cv2.waitKey(0)

Perintah ini digunakan agar gambar tetap di layar (tidak langsung closed ketika dibuka).
