  • Publication number: 20230077398
    Abstract: A tracking device includes full-spherical cameras arranged on the right and left. The tracking device pastes a left full-spherical camera image captured with the full-spherical camera on a spherical object, and is installed with a virtual camera inside the spherical object. The virtual camera may freely rotate in a virtual image capturing space formed inside the spherical object, and acquire an external left camera image. Similarly, the tracking device is also installed with a virtual camera that acquires a right camera image, and forms a convergence stereo camera by means of the virtual cameras. The tracking device tracks a location of a subject by means of a particle filter by using the convergence stereo camera formed in this way. In a second embodiment, the full-spherical cameras are vertically arranged and the virtual cameras are vertically installed.

  • Patent number: 11481919
    Abstract: An image recognition device includes: an image processing device that acquires a feature amount from an image; and an identification device that determines whether a prescribed identification object is present in the image, and identifies the identification object. The identification device includes a BNN that has learned the identification object in advance, and performs identification processing by performing a binary calculation with the BNN on the feature amount acquired by the image processing device. Then, the identification device selects a portion effective for identification from among high-dimensional feature amounts output by the image processing device to reduce the dimensions used in identification processing, and copies low-dimensional feature amounts output by the image processing device to increase dimensions.

  • Patent number: 11468572
    Abstract: An image processing device has a function for plotting a luminance gradient co-occurrence pair of an image on a feature plane and applying an EM algorithm to form a GMM. The device learns a pedestrian image and creates a GMM, subsequently learns a background image and creates a GMM, and calculates a difference between the two and generates a GMM for relearning based on the calculation. The device plots a sample that conforms to the GMM for relearning on the feature plane by applying an inverse function theorem. The device forms a GMM that represents the distribution of samples at a designated mixed number and thereby forms a standard GMM that serves as a standard for image recognition. When this mixed number is set to less than a mixed number designated earlier, the dimensions with which an image is analyzed are reduced, making it possible to reduce calculation costs.

  • Publication number: 20220189134
    Abstract: An image recognition device involves successively extracting co-occurrence pairs in synchronization with a clock, setting a weighting for the portion connecting the input layer and the intermediate layer corresponding to the extracted co-occurrence pairs, and successively inputting a first vote to the input layer. Meanwhile, the intermediate layer adds and stores the successively inputted number of votes. By continuing this operation, a value the same as if a histogram were inputted to an input layer is achieved in the intermediate layer, without creating a histogram. In this way, the image recognition device of this embodiment can perform image recognition while avoiding the creation of a histogram, which consumes vast amounts of memory. As a result of this configuration, it is possible to save memory resources, simplify circuits, and improve calculation speed, and achieve an integrated circuit suitable to an image recognition device.

  • Publication number: 20220180546
    Abstract: An image processing device can use a calculation formula based on an ellipse to approximate a base function of a reference GMM. The burden rate according to a co-occurrence correspondence point can be approximately determined by a calculation in which the Manhattan distance to the ellipse and the co-occurrence correspondence point and the width of the ellipse are input to a calculation formula for the burden rate based on the base function. The width of the ellipse is quantized by the nth power of 2 (where n is an integer of 0 or greater), and the calculation can be carried out by means of a bit shift.

  • Patent number: 11256950
    Abstract: An image processing device converts an image that is a recognition object image to high-resolution, medium-resolution, and low-resolution images. The device sets the pixel of interest of the high-resolution image, and votes the co-occurrence in a gradient direction with offset pixels, the co-occurrence in the gradient direction pixels in the medium-resolution image, and the co-occurrence in the gradient direction pixels in the low-resolution image, to a co-occurrence matrix. The device creates such a co-occurrence matrix for each pixel combination and for each resolution. The device executes the process on each of the pixels of the high-resolution image, and creates a co-occurrence histogram wherein the elements of a plurality of co-occurrence matrices are arranged in a line. The device normalizes the co-occurrence histogram and extracts, as a feature quantity of the image, a vector quantity having as a component a frequency resulting from the normalization.

  • Patent number: 11157724
    Abstract: An image recognition device executes a Hilbert scan of frame image data constituting moving-image data to generate one-dimensional spatial image data, and further arrays the one-dimensional spatial image data in a time direction to generate two-dimensional spatio-temporal image data that holds spatial information and temporal information. The image recognition device converts the moving-image data into the two-dimensional spatio-temporal image data while holding the spatial and temporal information. By means of a CNN unit, the image recognition device executes a convolution process wherein a two-dimensional filter is used on the spatio-temporal image data to image-recognize a behavior of a pedestrian who is a recognition object.
