non-photorealistic rendering for high quality tile art image generation with squares by pasting square patterns on canvas. Our technique is a method using the local search inspired by the characteristic of the human visual system to optimize generated images. Although it can generate high quality tile art images, a lot of time is necessary. Hence, we have proposed a parallel method using a graphics processing unit (GPU) to accelerate the computation. Also, for further speed-up, we have proposed an approximate tile art image generation method using machine learning. As a result, GPU implementation with the parallel method and GPU implementation with approximate method using machine learning can achieve a speed-up factor of 160 and 370000 over the sequential CPU implementation with parallel method, respectively.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告アルゴリズム（AL）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2018-08-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2018-AL-169"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
