Bộ mã hóa hình ảnh dựa trên sóng tần số thấp hiệu quả về tính toán cho Mạng cảm biến đa phương tiện không dây/Mạng Internet vạn vật (WMSNs/IoT)
Tóm tắt
Bài báo này đề xuất một sự điều chỉnh đơn giản và hiệu quả đối với thuật toán mã hóa hình ảnh nhúng phân vùng bộ nhớ bằng không tiên tiến nhất (ZM-SPECK) nhằm giảm bớt độ phức tạp tính toán mà không làm tăng đáng kể bộ nhớ. Đã quan sát rằng việc so sánh từng yếu tố của các khối/tập với ngưỡng hiện tại trong mỗi mặt phẳng-bit là một trong những quá trình tốn thời gian trong thuật toán ZM-SPECK. Đóng góp chính của bài báo này là tránh quá trình phức tạp về mặt tính toán đó bằng cách sử dụng độ lớn của hệ số lớn nhất trong mỗi subband, được tìm kiếm và lưu trữ trong quá trình tính toán biến đổi Wavelet rời rạc (DWT), trước khi mã hóa. Hơn nữa, tỷ số đỉnh-tín hiệu trên nhiễu (PSNR) của kỹ thuật đề xuất chính xác giống như tỷ số thu được bởi ZM-SPECK. Các kết quả mô phỏng cho thấy phương pháp đề xuất có thể giảm độ phức tạp của ZM-SPECK khoảng 29%, khiến nó phù hợp cho các nút cảm biến bị hạn chế tài nguyên trong các mạng cảm biến đa phương tiện không dây (WMSNs), Internet vạn vật (IoT), mạng khu vực cơ thể, v.v.
