Abstract:
A subject tracking method, includes: calculating a similarity factor indicating a level of similarity between an image contained in a search frame at each search frame position and a template image by shifting the search frame within a search target area set in each of individual frames of input images input in time sequence; determining a position of the search frame for which a highest similarity factor value has been calculated, within each input image to be a position (subject position) at which a subject is present; tracking the subject position thus determined through the individual frames of input images; calculating a difference between a highest similarity factor value and a second highest similarity factor value; and setting the search target area for a next frame based upon the calculated difference.
Abstract:
A microcontroller is disposed on a receiving part of a wireless system in order to process a demodulation signal generated by a receiver circuit, and includes a memory and a CPU. The memory stores a control program of the microcontroller. The control program thereof includes a dual loop routine for an operation in reception standby mode. The dual loop routine has a first loop and a second loop included in the first loop. The CPU has an instruction set consisting of a plurality of instructions, and executes the instructions according to the program stored in the memory. The CPU executes an instruction irrelevant to an operation when the microcontroller is in reception mode during the second loop a number of times. The number of times is at least such that noise caused by the repetition of the second loop is lowered below a desired level.
Abstract:
A photometric device includes: an imaging unit that captures an image formed by an optical system, with a marker capable of switching between display and non-display disposed in a light path of the optical system; and a correction unit that, based upon a difference between a first image captured by the imaging unit in a state where the marker is displayed and a second image captured by the imaging unit in a state where the marker is not displayed, performs a correction of a third image that is different from the first image and the second image.

Abstract:
An image matching device includes: a dividing unit that divides a target image, contained in a search window set within an input image constituted with pixels each having a luminance component and a chrominance component, and a template image constituted with pixels each having the luminance component and the chrominance component, each into a plurality of divided areas; a representative value calculation unit that calculates a luminance component representative value and a chrominance component representative value in correspondence to each of the divided areas; a normalizing unit that normalizes the luminance component representative value having been calculated in correspondence to each divided area; and a template matching processing unit that executes template matching processing based upon the normalized luminance component representative value and the chrominance component representative value corresponding to each of the divided areas in the template image, and upon the normalized luminance component representative value and the chrominance component representative value corresponding to each of the divided areas in the target image.
Abstract:
A sound increase apparatus includes a partition wall adapted to divide an engine room for defining a first engine room space that is located on a side of a dash panel and a second engine room space in which an engine is installed, and a first pressure fluctuation amplification unit inter-communicating an engine inlet pipe arranged in the second engine room space and the first engine room space. The first pressure fluctuation amplification unit amplifies a pressure fluctuation of a first frequency selected from a plurality of frequencies when pressure of air residing inside the engine inlet pipe fluctuates at the plurality of frequencies.
Abstract:
An electrophoretic display device includes pixels each including an electrophoretic element that has a pixel electrode, an opposing electrode that faces the pixel electrode, and an electrophoretic layer that is configured by electrophoretic particles disposed between the pixel electrode and the opposing electrode. The pixels are arranged two-dimensionally, and an insulating layer formed of a photosensitive insulating material is disposed in areas between the adjacent pixel electrodes.
Abstract:
A binary mask image for extracting subject is generated by binarizing an image after image-processing (processed image) with a predefined threshold value. Based on an image before image-processing (pre-processing image) and the binary mask image for extracting image, a subject image in which only a subject included in the pre-processing image is extracted is generated by eliminating a background region from the pre-processing image.
Abstract:
A computer performs following steps according to a program for tracking an object. Template matching of each frame of an input image to a plurality of template images is performed, a template image having a highest similarity with an image within a predetermined region of the input image is selected as a selected template among the plurality of template images and the predetermined region of the input image is extracted as a matched region. With reference to an image within the matched region thus extracted, by tracking motion between frames, motion of an object is tracked between the images of the plurality of frames. It is determined as to whether or not a result of template matching satisfies an update condition for updating the plurality of template images. In a case that the update condition is determined to be satisfied, at least one of the plurality of template images.
Abstract:
An amplification device for amplifying suction noise of a vehicle is disclosed herein. An embodiment of the amplification device comprises an intake duct, a connecting pipe, an elastic membrane member and a contact member. The intake duct feeds air into an engine inlet port. A connecting pipe is connected to an interior of the intake duct. The elastic membrane member blocks a passageway inside of the contacting pipe. The contact member is connected to the connecting pipe and includes at least one portion that is adapted to selectively contact a surface of the elastic membrane member that faces the intake duct.
