Image processing apparatus and control method of the same
A low-resolution image having a low resolution and low frequency band is generated from an image sensed by using a single board color image sensor, and pseudo color suppression and color noise suppression are performed on each of the image and low-resolution image. The resolution of the low-resolution image is then restored, and weighted combination is performed on this image and the former image. If it is determined that a pixel of interest belongs to a region where a pseudo color is generated, a MIX ratio calculator (205, 225) for calculating a ratio coefficient for combination calculates a ratio coefficient by which a color signal of a pixel of the low-resolution image having the restored resolution is the result of the weighted combination. This makes it possible to effectively suppress both a pseudo color and color noise. |

Capacity on-demand in distributed computing environments
Methods, systems, computer program products, and methods of doing business by using dynamic capacity-on-demand techniques for re-routing traffic in a distributed computing network.

Optimizing evaluation patterns and data acquisition for stream analytics in resource-constrained wireless environments
Mobile wireless devices may receive data streams from multiple remote sensors. The sensors may have limited power supplies and memory capacity. Aspects of the invention use statistical characteristics of the sensor data streams and the cost of acquiring a single element of each stream to determine what sequence the sensors should send their data streams in. The cost of acquiring the data may be modified dynamically, depending on parameters such as block size. Additional factors, such as a sensor's buffer capacity, may limit the amount of stream elements that may be cached and affect the sensors' stream transmit sequence. The evaluation order may be dynamically modified using an event processing engine, to reflect both changing statistics of underlying sensor stream tuples and time-varying acquisition costs associated with individual streams. This helps to increase in the operational lifetime of the sensors and associated monitoring applications. |

Rapid data encryption and decryption for secure communication over open channels with plausible deniability
Technologies are generally described for providing rapid data encryption and decryption for secure communication over an open channel with plausible deniability.

Scalable method of proportional active state of charge balancing for managing variations in the state of health of batteries
A method and system for power management among batteries of varying states of health. Two or more battery packs are switched on and off in square wave pulses to energize a multi-winding transformer, and the output of the transformer is used to power a load. As the state of charge of the battery packs decrease at different rates, the duty cycle of each battery pack's switch pulse is made proportional to its state of charge relative to the other battery packs. The battery pack with the greatest state of charge has the longest on-time and provides the most energy to the transformer, yet all battery packs contribute. A baseline duty cycle is computed by a proportional integral control module, based on voltage measurements at the load. Energy contribution is managed so that state of charge does not diverge even when the battery packs have widely varying states of health. |
