方向背景

人腦是已知最有效的生物智慧型系統,它具有感知、學習、聯想、記憶、推理等功能,它對信息與知識的處理、加工與利用能力遠遠超過現有的任何計算機和信息處理系統。要使計算機能夠像人一樣處理複雜的信息和數據,必須發展具有人類智慧型的信息分析技術。研究具有認知機理的智慧型信息處理理論與方法,探索大腦信息加工的認知過程和神經機制,探討和實現新的神經計算模型,建立物理可實現的計算模型必將為信息技術的發展注入新的活力。與此同時,信息獲取、處理與分析的最新研究成果的運用,已經並將進一步促進腦科學與認知科學的發展,從技術和方法學的層面為腦科學與認知科學研究提供不可或缺的手段。

視覺是人類獲取信息的最直接與最主要的手段,是智慧型人機互動的重要通道。圖像作為視覺信息的重要載體,其內容分析與理解是開發新一代智慧型機器人、自動目標跟蹤系統和實時人機互動界面等研究領域的核心技術之一。面對圖像處理的複雜性和工程套用的苛刻性,傳統的圖像處理技術面臨著巨大挑戰。探索生物視覺的感知與整合機理,建立視覺計算模型框架與推理引擎對解決圖像和視頻內容提取、精煉與解析、多媒體信息檢索問題,以及基於視覺感測的環境感知與理解都具有重大實際套用價值。
