基本信息
博士、教授,現任中山大學軟體學院副院長,中山大學“百人計畫”引進人才。
研究興趣:數字圖像處理,視頻數據壓縮、編碼和通信,數字媒體技術。其中包括圖像增強、圖像分析、圖像識別、運動預測、運動補償等。
曾經作為負責人承擔過多項國家自然科學基金、國家重大項目、青年科學基金等項目,其中包括:一項年國家青年科學基金(負責人)、兩項國家自然科學基金(負責人)、一項中山大學自然科學基金(合作)、一項國家重大項目三級子課題(負責人)。在美國曾作為美國海軍兩項科研基金(共150萬美金)的技術負責人。現正在承擔台灣致伸科技公司項目“數字圖像處理中的關鍵技術”、微軟亞洲研究院項目“微軟WinCE平台移動遊戲引擎開發中的自然景物模擬”以及美國ESPRE公司視頻壓縮標準最佳化項目。863導向類專題項目“基於動漫資料庫的計算機輔助動畫動漫創作關鍵技術”,已獲科技部批准。
在美國軟體行業工作近8年,研發數個數字圖像和視頻產品。這些產品目前已被Oracle(甲骨文)、百度(即時通訊)等國內外若干大公司簽約使用。發表論文近20篇,有三項美國專利局專利獲批准。
學術兼職:
□ IEEE會員(2004~)、
主講課程:
數字圖像處理、線性代數、視頻圖像理解與分析
研究生招生:
□ 碩士生:計算機套用技術、軟體工程
□ 博士生:計算機套用技術
教學評價:
對待學生態度很好,而且教書的時候總是為學生著想。
講課內容豐富,深入淺出,很受益。老師對學生要求嚴格且非常負責。學習有壓力。如果你想學知識,對你來說她是一個好老師,如果你純粹是為了拿學分,對不起,不要進入她的課堂,否則作業會讓你喘不過氣,考試會讓你如臨深淵,數字圖像處理1/3掛科率不是吹出來的……
