PROGRAM JAVA KONTRAS CITRA -PENGOLAHAN CITRA SHARPEN DAN BLUR

SM Society, kali ini akan memposting artikel tentang program java yang berkaitan dengan pengolahan citra digital yaitu Sharpen dan Blur, dimana program ini mengubah warna citra sebuah gambar.

Berikut Listing programnya, dengan menggunakan JCreatro sebagai aplikasi untuk menjalankan dan melihat hasilnya. Dan kemudian simpan dengan extensi Kontras_Citra.java :
