An image processing apparatus includes a projecting unit that projects a registered face image containing at least part of a face onto a surface of a three-dimensional model having a shape in which at least part of the three-dimensional model in one direction on the surface onto which an image is projected is bent to a front side, so that a horizontal direction of the face contained in the registered face image substantially coincides with the one direction, a transforming unit that transforms the three-dimensional model on the basis of an orientation of a face contained in a target image, a generating unit that generates a two-dimensional image by projecting the registered face image projected on the surface of the transformed three-dimensional model, onto a plane, and an identifying unit that identifies the face contained in the target image, by comparing the generated two-dimensional image against the target image.

A classification result is stored in advance. At the time of identification, classification is performed at a high speed based on the stored classification result. In pre-classification, classification is performed divisionally in two stages. In the first classification, a plurality of representative vectors are generated from the classification result using a fast executable method. In the second classification, the created representative vectors are classified, and the result is stored in a lookup table. When an identification target image is input, the classification result can be reflected at a high speed by using the lookup table.

An image processing method correcting a defective portion in color image data having a plurality of color components. The method includes the steps of adjusting luminance of each defective pixel; selecting a plurality of normal pixels from around a target pixel which is selected from a plurality of defective pixels; obtaining for each color component, a difference between a pixel value of the target pixel whose luminance has been adjusted by the luminance adjusting unit and a corresponding pixel value of each normal pixel selected; obtaining a minimum value of the differences for the respective color components of each normal pixel, thereby to obtain a weight coefficient common to the respective color components for each normal pixel, the smaller the minimum value, the greater a weight being provided by the coefficient; calculating a weighted average value for each color component of the plurality of normal pixels by using the weight coefficient; and correcting the target pixel by using the weighted average value for each color component.

To provide an image processor, an image processing method, and an image processing program, none of which require special hardware implementation and installation of a program requiring a large calculation amount. An embodiment of the present invention relates to an image processor for representing a shaded space defined by an object in a 3D space blocking light from a light source, which generates boundary data including positional information on the light source and positional information on the object to calculate the brightness of the shaded space based on the generated boundary data. With such a structure, the shaded space can be represented as boundary data in the same form as the object data, making it possible to reflect the brightness of the shaded space in a display image through the same processing as object rendering without any special hardware implantation, suppress a calculation amount, and improve an image quality.

The invention relates to an impact sound-based automatic traffic accident detection method. The method comprises the following steps of: framing an acquired sound signal, detecting the total energy distribution of a time domain, and performing further recognition if an impact condition is met and directly stepping out and waiting for the processing of a next frame if the impact condition is not met; judging the energy distribution of a frequency domain, extracting and judging an energy distribution characteristic component by using wavelets, performing further recognition if the impact condition is met and directly stepping out and waiting for the processing of the next frame if the impact condition is not met; and performing advanced communication function (ACF) detection, judging an impact sound if the impact condition is met or waiting for the processing of the next frame. The method has the advantages of improving detection accuracy, lowering misstatement rate and minimizing calculated amount.

The present invention provides an image processing device and an environmental information observation device capable of performing highly versatile information processing based on two-dimensional images. The image processing device has: a two-dimensional image information acquisition unit that acquires two-dimensional image information of a subject (2); and a three-dimensional space information acquisition unit that acquires three-dimensional space information composed of a set of latitude, longitude, and altitude of the subject. An image display unit (17) for displaying a two-dimensional image; an image information synthesis unit (26) for synthesizing the obtained two-dimensional image information and three-dimensional space information; an attribute information imparting unit (27). An attribute information imparting unit (27) assigns at least one attribute information consisting of a set of latitude, longitude, and altitude of the subject (2) to each pixel of the two-dimensional image.

An ultrasound diagnostic apparatus performs transmission and reception of ultrasonic waves for forming focal points used to set sound velocities at predetermined timing such that sound velocities having been set for all of respective segment regions established by diving a subject are all reset every predetermined number of frames. Owing to this configuration, it becomes possible for the ultrasound diagnostic apparatus to suitably reset sound velocities of ultrasonic waves in the subject and also reduce the amount of calculation for resetting sound velocities.

There is presented systems and methods to present air traffic and other related hazards on a flight deck display in a manner that presents relevant aircraft that may be of interest to flight deck personnel at a future time, accompanied with decluttering the display by removing information pertaining to aircraft that are of lesser impact to the safe navigation of an ownship aircraft. The improved avionics system of the present invention can make decisions that are more intelligent on how to best present traffic information to a flight crew in a manner that improves upon the prior hardware processes and increases efficiency of operation of the avionics hardware and processing system by presenting relevant information and suppressing unnecessary computation and modification of display elements.

The purpose of the present invention is to more assuredly generate a system construction procedure, while reducing the amount of calculation. This system construction assistance system is provided with: a state model dividing unit 501 that divides state models into one or more groups, on the basis of at least the dependency between state elements included in the state models; a invertibility determination unit 502 that determines the invertibility of a set of state elements belonging to a specified group; a group dependent procedure calculation unit 503 that calculates, for each group after division, a procedure for transitioning the set of state elements belonging to the group to a requested state; and a procedure integration unit 504 that integrates the procedures calculated for each group.
