Patent number: 11468572Abstract: 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.Type: GrantFiled: January 31, 2018Date of Patent: October 11, 2022Assignees: AISIN CORPORATION, KYUSHU INSTITUTE OF TECHNOLOGYInventors: Hideo Yamada, Kazuhiro Kuno, Masatoshi Shibata, Shuichi Enokida, Hiromichi Ohtsuka

Publication number: 20220189134Abstract: 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.Type: ApplicationFiled: March 30, 2020Publication date: June 16, 2022Applicants: AISIN CORPORATION, KYUSHU INSTITUTE OF TECHNOLOGYInventors: Hideo YAMADA, Ryuya MURAMATSU, Masatoshi SHIBATA, Hakaru TAMUKOH

Publication number: 20220180546Abstract: 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.Type: ApplicationFiled: March 30, 2020Publication date: June 9, 2022Applicants: AISIN CORPORATION, KYUSHU INSTITUTE OF TECHNOLOGYInventors: Hideo YAMADA, Masatoshi SHIBATA, Hakaru TAMUKOH, Shuichi ENOKIDA, Kazuki YOSHIHIRO

Patent number: 11256950Abstract: 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.Type: GrantFiled: January 31, 2018Date of Patent: February 22, 2022Assignees: AISIN CORPORATION, KYUSHU INSTITUTE OF TECHNOLOGYInventors: Hideo Yamada, Kazuhiro Kuno, Masatoshi Shibata, Shuichi Enokida, Hakaru Tamukoh

Patent number: 11017262Abstract: A hardware configuration is constructed for calculating at high speed the co-occurrence of luminance gradient directions between differing resolutions for a subject image. In an image processing device, a processing line for high-resolution images, a processing line for medium-resolution images, and a processing line for low-resolution images are arranged in parallel, and the luminance gradient directions are extracted for each pixel simultaneously in parallel from images having the three resolutions. Co-occurrence matrix preparation units prepare co-occurrence matrices by using the luminance gradient directions extracted from these images having the three resolutions, and a histogram preparation unit outputs a histogram as an MRCoHOG feature amount by using these matrices. To concurrently processing the images having the three resolutions, high-speed processing can be performed, and moving pictures output from a camera can be processed in real time.Type: GrantFiled: March 30, 2017Date of Patent: May 25, 2021Assignees: EQUOS RESEARCH CO., LTD., KYUSHU INSTITUTE OF TECHNOLOGYInventors: Hideo Yamada, Kazuhiro Kuno, Hakaru Tamukoh, Shuichi Enokida, Shiryu Ooe
