Hệ thống thông tin đa phương tiện đã được sử dụng rộng rãi và đa dạng trong các nghiên cứu và ứng dụng thực tế. Trong đó, dữ liệu video là một trong những kiểu dữ liệu phổ biến nhất. Tuy nhiên, việc quản lý và sử dụng dữ liệu video gặp nhiều vấn đề như việc tổ chức lưu trữ, hay tìm kiếm sự kiện trong một video. Do đó, nghiên cứu này sẽ trình bày một phương pháp tóm tắt video hiệu quả và đơn giản, sử dụng kỹ thuật trừ nền. Đầu tiên, video đầu vào được sử dụng để trích xuất các khung ảnh liên tiếp. Sau đó, các khung ảnh này sẽ được tiền xử lý, như chuyển sang ảnh đa mức xám và làm mịn ảnh. Kỹ thuật trừ nền được sử dụng để phát hiện chuyển động trong khung ảnh hiện tại so với khung ảnh ngay trước đó. Nếu khung ảnh có phát hiện chuyển động thì nó sẽ được lưu lại cho video đầu ra. Chúng tôi cũng đề xuất một thuật toán tóm tắt video. Các kết quả thực nghiệm cho thấy tính hiệu quả của phương pháp này, đặc biệt đối với các video giám sát.
