Image conversion device, image conversion method, program and electronic apparatus

Abstract: PROBLEM TO BE SOLVED: To eliminate the limit of a processable image size caused by the memory capacity of a memory unit to be used for conversion processing in an image conversion device.SOLUTION: An enlargement/reduction processor 16 includes: an acquisition unit 21 for acquiring pixel data of a plurality of pixels specified in a matrix shape to an image; a line memory 22 for storing the acquired pixel data; and an interpolation filter 23 for enlarging or reducing the acquired input image into an output image, by increasing/decreasing the number of pixels constituting the image using the pixel data stored in the line memory 22. The acquisition unit 21 reads the pixel data of the plurality of pixels included in each row of the input image separately into a plurality of times. The interpolation filter 23 executes enlargement processing or reduction processing to increase/decrease the number of pixels, in order of the pixels read into the line memory 22.

Image collation device, image collation method, and image collation program

Abstract: PROBLEM TO BE SOLVED: To provide an image collation device, an image collation method, and an image collation program which collate images with high accuracy.SOLUTION: The image collation device includes: a piece of paper registration unit 21 for registering an image of a registered piece of paper; and a piece of paper identification unit 22 for collating an image of a collated piece of paper with the image of the registered piece of paper. In image collation processing for extracting characteristic points of the images and calculating and collating image conversion parameters using the characteristic points, the collation of the images is performed while successively exchanging estimated parameters by estimating validity of the images estimated by the image conversion parameters. In order to cope with a local revolution and expansion and contraction, the whole images are collated by recursively performing processing of correlating corresponding points not correlated with each other with a pair of image conversion parameters by separate parameters.

Vehicle model discriminating device

Abstract: PROBLEM TO BE SOLVED: To provide a vehicle model discriminating device for more accurately discriminating a vehicle model of a vehicle. SOLUTION: This vehicle model discriminating device 1 for discriminating the vehicle model of the vehicle 10 has: a camera 11 and a laser radar 12 for imaging the vehicle 10; a projected plane estimation part 13 for setting a projected plane PA when the vehicle 10 is imaged from a direction different from an imaging direction of the camera 11 and the laser radar 12; an image conversion part 14 for projecting the picked up image imaged by the camera 11 and the laser radar 12 onto the projected plane PA set by the projected plane estimation part 13, and converting the picked up image; an image accumulation part 15 for accumulating a plurality of frames converted by the image conversion part 14; and a silhouette extraction part 16 for detecting a silhouette of the vehicle 10 based on the plurality of frames accumulated by the image accumulation part 15 to discriminate the vehicle model.
