In this paper, we propose an encryption method to secure the multiple regions of interest (ROIs) of scalable video coding (SVC) bitstream from malicious attacks and a key generation scheme to control the protected ROIs conditionally. To establish the encryption method, we analyze the encryption requirements to maintain spatial, temporal, and SNR scalability of SVC. Depending on the given user’s condition...
In the paper, a smartphone-controlled riding robot based on a compass sensor is developed. A smartphone-controlled riding robot system using a magnetic compass sensor makes a riding robot move with heading direction of a smartphone is controlled by a rider. The smartphone-controlled riding robot system gives an interface that is more intuitive than controlled by pushing a button through using a compass...
This study proposes a sensing glove interface for the remote control of a board robot based on Bluetooth wireless communication. A board robot is a type of user-controlled riding robot. The user can use the glove to remotely control the robot's direction through five commands based on different finger actions — “1” = right, “2” = neutral/straight, “3” = left, “4” = start/operation, and “5” = stop...
In this study, an attempt has been made to incorporate visual cooperation among decentralized swarm robots for self-organization. Self-organization based on color recognition is presented to overcome the constraints faced in conventional self-organization based on centralized control, in which an external ceiling camera or beacon systems are used. In the proposed scheme, a singular association rule...
In this research, dynamic equations a WIP (Wheeled Inverted Pendulum) changing center of gravity when some load or equipment on the WIP are changing. The WIP becomes a popular platform for mobile robots which should be equipping various load and apparatus on it. The WIP generally has two equilibrium points which are stable and unstable. The WIP should be stabilizing over the unstable equilibrium point...
This paper discusses new approach to materialize for automation test method for automotive embedded software. The total automotive embedded software is changing frequently whenever the specification for hardware is modified. These cause to spend time and cost. To resolve these problems, AUTOSAR which consists of the standardized interfaces, structures and communication method was introduced. AUTOSAR...
In this paper, we propose an encryption method to protect the region of interest (ROI) which is standard element in the scalable video coding (SVC). The proposed video encryption method provides secured SVC contents with the selective encryption scheme. In order to confine the encryption into the ROI, three encoding schemes are also proposed, which include the constrained motion estimation, exceptional...
