人腦是已知最有效的生物智能系統(tǒng)，它具有感知、學習、聯(lián)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(xiàn)有的任何計算機和信息處理系統(tǒng)。要使計算機能夠像人一樣處理復(fù)雜的信息和數(shù)據(jù)，必須發(fā)展具有人類智能的信息分析技術(shù)。研究具有認知機理的智能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(jīng)機制，探討和實現(xiàn)新的神經(jīng)計算模型，建立物理可實現(xiàn)的計算模型必將為信息技術(shù)的發(fā)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(jīng)并將進一步促進腦科學與認知科學的發(fā)展，從技術(shù)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，是智能人機交互的重要通道。圖像作為視覺信息的重要載體，其內(nèi)容分析與理解是開發(fā)新一代智能機器人、自動目標跟蹤系統(tǒng)和實時人機交互界面等研究領(lǐng)域的核心技術(shù)之一。面對圖像處理的復(fù)雜性和工程應(yīng)用的苛刻性，傳統(tǒng)的圖像處理技術(shù)面臨著巨大挑戰(zhàn)。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(nèi)容提取、精煉與解析、多媒體信息檢索問題，以及基于視覺傳感的環(huán)境感知與理解都具有重大實際應(yīng)用價值。
