Source Code Representasi Citra Pertemuan 2
1. Import Library
argparse → untuk parsing argumen dari command line (CLI). os & sys → mengatur path, direktori, dan sistem. cv2 → OpenCV, dipakai untuk manipulasi dan konversi citra (misalnya RGB ke grayscale). tkinter → GUI sederhana (popup dialog, pesan info). filedialog & messagebox → komponen GUI untuk memilih file dan menampilkan pesan. 2. Setup path agar bisa impor modul lokal
_FILE_DIR → folder tempat file Python ini berada. _ROOT_DIR → folder induk (parent) dari file ini. sys.path.insert(...) → menambahkan root project ke path Python, supaya bisa impor modul common. 3. Import modul internal
read_image → fungsi khusus untuk membaca gambar dari path. show → fungsi khusus untuk menampilkan gambar (dengan jendela GUI/plot). 4. Fungsi utilitas: statistik
Input: channel (array piksel, misalnya R, G, B atau grayscale). Output: string berisi statistik → nilai minimum, maksimum, dan rata-rata intensitas. Contoh output: R -> min:0 max:255 mean:123.45. 5. Fungsi utama
args.image → path gambar dari CLI (jika ada). a. Pilih file lewat GUI jika tidak ada argumen
Jika tidak ada argumen --image atau user pakai --gui, maka buka dialog pilih file. Jika user batal → tampilkan pesan "Tidak ada file yang dipilih.". b. Baca gambar & pisahkan channel
read_image → membaca gambar ke array numpy. R, G, B → ekstrak tiap channel warna. gray → konversi ke grayscale dengan OpenCV. c. Hitung statistik intensitas
Menghitung statistik tiap channel. Cetak ke terminal. d. Tampilkan statistik lewat GUI
Cek apakah ada root Tkinter aktif. Jika tidak, buat root baru sementara. Tampilkan statistik dalam popup GUI. Hancurkan root sementara setelah selesai agar tidak ada jendela kosong. e. Tampilkan channel satu per satu
Memanggil show untuk menampilkan tiap channel dengan labelnya. 6. Entry Point (jalankan script)
Membuat parser argumen: --image → path file gambar (opsional). --gui → flag untuk membuka dialog file. Panggil main(args) dengan argumen tersebut. Ringkasan
Script ini berfungsi untuk:
Membaca gambar dari argumen CLI atau dialog GUI. Memisahkan channel R, G, B, Grayscale. Menghitung statistik intensitas (min, max, mean). Menampilkan statistik di terminal dan GUI popup. Menampilkan channel secara visual satu per satu.
