    We propose accelerated implementations of bilateral filter (BF) and nonlocal means (NLM) called color-compressive bilateral filter (CCBF) and color-compressive nonlocal means (CCNLM). CCBF and CCNLM are random filters, whose Monte-Carlo averaged output images are identical to the output images of conventional BF and NLM, respectively. However, CCBF and CCNLM are considerably faster because the spatial processing of multiple color channels are combined into a single random filtering process. This implies that the complexity of CCBF and CCNLM is less sensitive to color dimension (e.g., hyperspectral images) relatively to other BF and NLM methods. We experimentally verified that the execution time of CCBF and CCNLM are faster than the existing fast implementations of BF and NLM, respectively

    本稿は 2008 年9 月21 日〜23 日に埼玉県県民活動総合センターで開催された第8 回ビジュアル情報処理研究合宿(以下、本合宿)の報告である。本合宿は、他大学の学生と議論する場の提供および大学の枠を越えた学生ネットワークの形成を目的として、運営委員と呼ばれる有志学生によって企画・運営された。本合宿での主な活動内容は、学生によるポスター発表、社会人を含めた登壇発表、レクリエーション、懇親会である。新たな試みとして、本年度は、ソーシャルネットワーキングサービスによる事前交流、国際会議に倣ったアルコールを伴う英語セッションを取り入れた。参加者に実施したアンケートから、91%の学生が本合宿に対して満足であったことがわかった。This paper is a report of 8th Visual Information Processing Camp. This camp was held from 21st till 23rd of September 2008. Voluntary students planed and managed this camp. The purpose of this camp is to make up the network and to make the discussion between students from different university. The topic of this camp was poster session, oral session, recreation and get-together party. The new attempts were a pre-communication used Social Networking Service and an English session drinking. As the result, from the answer of questionnaire, 91 0x800articipants were satisfied
