澳大發展基金會傑出學人教授桂長峰談數學樂趣與挑戰

澳門大學今(21)日舉行“澳門大學發展基金會傑出學人講座",由澳大發展基金會數學傑出學人教授、澳大科技學院數學系講座教授暨系主任桂長峰以“數學及其應用:樂趣與挑戰”為題發表演說。講座線上線下同步舉行,吸引一眾澳大師生及公眾人士參與。

澳大代校長許敬文致辭時表示,桂長峰是備受尊敬的數學界知名學者,擁有逾30年教研經驗,曾在美國、加拿大、中國等地從事教研工作。今年年初加入澳大前,乃美國德州大學聖安東尼奧分校丹.帕爾曼應用數學冠名講座教授。他以研究非綫性偏微分方程、圖像分析和處理見稱,研究成果均發表在極具競爭力的國際著名學術期刊。他在學術服務上也貢獻良多,建立了良好的國際聲譽,曾獲得多項獎項和榮譽,其中包括西蒙斯會士、IEEE信號處理協會最佳論文獎、首屆美國數學學會會士等。許敬文表示,桂長峰作為數學系系主任,將帶領該系在作育英才及科研上邁向新台階。

講座上,桂長峰針對關鍵問題進行深入淺出的探討,例如數學是甚麼、數學為何重要等。由於數學是多個科技領域的基礎,其重要性及關聯性使之趣味盎然而複雜多變,充滿著難題和挑戰,有待不斷探索和解難。他也從自身理解和經驗出發,分享其獨到見解,並以幾何學、物態變化、圖像處理之間的關聯作例,展現數學在教與學以至研究方面的樂趣和挑戰。他進而從其研究專長圖像處理為例,闡述圖像處理乃是一種數學運算,廣泛應用於諸如X光、磁力共振、電腦掃描、超聲波等醫療用途上。而應用數學可用於以下圖像處理的優化:例如圖像增強和去噪、圖像去模糊、圖像分割、圖像修復等,令圖像質量得以提升。

其後,澳大科技學院數學系副教授胡光輝主持問答及交流環節,講者和與會者積極交流互動,討論氣氛熱烈。
