Akuisisi citra digital menggunakan webcam


Matlab (Matrix Laboratory) merupakan salah satu perangkat lunak yang mendukung bidang pengolahan citra digital. Dalam bidang tersebut pada umumnya diawali dengan proses akuisisi citra digital.

Proses akuisisi citra digital dilakukan dengan cara menangkap (capture) atau memindai (scan) citra analog kemudian mengkonversinya menjadi citra digital agar dapat disimpan dan juga diolah melalui komputer.

Salah satu alat akuisisi citra digital yang sering digunakan adalah webcam.

Dalam software Matlab, proses akuisisi citra digital menggunakan webcam dapat dilakukan dengan terlebih dahulu menginstal driver Image Acquisition Support Packages for Hardware Adaptors.

Ada cukup banyak driver yang perlu diinstal yaitu sebagai berikut:
