Abstract: A microneedle array to be used instead of a syringe has, at a tip side of each microneedle, two or four puncture portions disposed facing each other. The puncture portions each have a part of a side surface of each microneedle as outer surfaces, respectively, and one of the puncture portions is shorter than the other(s). A housing section capable of holding a drug is formed by inner surfaces of the puncture portions of each microneedle. The housing section opens toward the tip side and lateral directions orthogonal to an axis core of each microneedle, and has a central bottom surface at a bottom end. The inner surfaces facing each other and forming the housing section of each microneedle each have a downward slope, with a width between the inner surfaces getting narrower as it goes down from tips of the respective puncture portions toward the central bottom surface.

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.

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.

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.

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.
