In this paper, we propose a data embedding method into still images based on Vector Quantization (VQ). In recent years, several VQ-based data embedding methods have been proposed. For example, `Mean Gray-Level Embedding method (MGLE)' are `Pair wise Nearest-Neighbor Embedding method (PNNE)' are simple, but not sufficiently effective. Meanwhile, an efficient adaptive data hiding method called `Adaptive...
It is fundamental work to translate the historical characters called "kuzushi-ji" into the contemporary characters in Japanese historical studies. In this paper, we develop the Japanese historical character recognition system using the directional element features and modular neural networks. Modular neural networks consist of two kinds of classifiers: a rough classifier to find the several...
Responsive Link, an ISO/IEC communication standard, provides many functional capabilities for distributed realtime systems. This paper is focused on periodic and aperiodic communication techniques for Responsive Link. In periodic communication, the priority is assigned to each packet so that the network utilization is improved. A schedulability test for connection establishments is also derived to...
This paper presents a new algorithm for scheduling of sporadic task systems with arbitrary deadlines on identical multiprocessor platforms. The algorithm is based on the concept of semi-partitioned scheduling, in which most tasks are fixed to specific processors, while a few tasks migrate across processors. Particularly, we design the algorithm so that tasks are qualified to migrate only if a task...
This paper presents an algorithm, called Earliest Deadline Critical Laxity (EDCL), for the efficient scheduling of sporadic real-time tasks on multiprocessors systems. EDCL is a derivative of the Earliest Deadline Zero Laxity (EDZL) algorithm in that the priority of a job reaching certain laxity is imperiously promoted to the top, but it differs in that the occurrence of priority promotion is confined...
Robust fast continuous path tracking control is the important technology for the multi-degrees-of-freedom position control system such as X-Y table, robot manipulator and so on. Especially, large acceleration and/or deceleration torque is necessary for fast continuous path tracking control at its start position and its goal position. Each motor of high speed path tracking control has the torque limitation...
