IMAGE PROCESSING Using MATLAB Tại sao lại dùng matlab? Matlab (MATrix LABoratory) Ảnh trong matlab được xử lý như là ma trận Mỗi pixel là một phần tử của ma trận Tất cả các toán tử trong matlab đều tác động lên ma trận và có thể được dùng để tác động lên ảnh: +, -, *, /, ^, sqrt, sin, cos, etc. Tài Liệu 1) Digital image processing using Matlab, Rafael C.
