Abstract: A system and method for comparing and searching for digital data, such as images, using histograms includes receiving a source image, receiving a comparison image, generating a first histogram for the source image and generating a second histogram for the comparison image. The source image may be received from a network device, such as a computer or camera, and the comparison image may one of a plurality of stored images in a database. The histograms may correspond to an image characteristic, including a color histogram corresponding to the distribution of the intensity of a corresponding color among image pixels in the source image. Each of first and second histograms is normalized and a similarity score is calculated between the two histograms. The similarity score represents a similarity measure between the two histograms, calculated from a subset of bins, which are independently selected for each image.

Abstract: According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry obtains first and second blood vessel image by image generation processing which obtains time phase changes in concentrations of a contrast agent based on X-ray contrast image and generates time phase image according to a gray or color scale. The time phase image has pixel values corresponding to time phases at which the concentrations of the contrast agent become a specific condition. The image generation processing is performed multiple times based on X-ray contrast images acquired at different times. Further, the processing circuitry determines or corrects pixel values or time phases of at least one of the first and second blood vessel image, to make a pixel value of a time phase of the first blood vessel image coincident with that of the second blood vessel image.

Abstract: A method and apparatus is provided to generate two X-ray projection images, using different focal-spot sizes in the X-ray source. The large and small focal-spot images have different image qualities (e.g., different signal-to-noise rations (SNR) and different resolution). The two images are combined, in either the spatial or frequency domains, to generate a combined image, exhibiting the best attributes of the constitutive small and large focal-spot images. In the spatial domain, change regions and uniform regions are determined based on spatial variations within the images, and the superposition generating the combined image weights the small focal-spot image more in the change regions and the large focal-spot image more in the uniform regions. In the frequency domain, the combined image superimposes low-frequency components of the large focal-spot image with high-frequency components of the small focal-spot image.

Abstract: A power transfer electrical system includes an electrical signal source that generates a current at an output. An electrical load is electrically connected to the output of the electrical signal source. An output of a controllable voltage source is also electrically connected to the electrical load. The controllable voltage source generates a voltage that is proportional to the current generated by the electrical signal source. An input of a controller is electrically connected to the output of the electrical signal source and an output of the controller is electrically connected to a control input of the controllable voltage source. The controller generates a signal that controls the voltage generated by the controllable voltage source so that a desirable amount of power is transferred from the electrical signal source to the controllable voltage source.

Abstract: The present invention relates to a vehicle recorder system that is configured with a video camera, a light weight memory system, and a radio communications facility suitable for use in conjunction with an moving vehicle. An automobile equipped with such video recorder system that is used throughout a day of service provides a video record of unusual events which may occur from time-to-time. For example, events such as accidents, near-misses, and excessive speed, among others, trigger a system to preserve video images collected before and after the moment of the event. Replaying these images provides information regarding the cause and true nature of the event. These systems are particularly suitable for vehicle fleets, or other groups of vehicles that can communicate with a common system.
