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
