主要研究領域:

數位信號處理、數位影像處理

Major Research Areas:

Digital Signal Processing, Digital Image Processing

研究領域摘要:

1. 數位影像處理

  包括物件識別,模糊影像還原,顯著區域偵測, 角與邊緣偵測,影像壓縮,浮水印,影像加密 

2. 影像壓縮  

 

3. 時頻分析

  包括韋格納分佈方程式,加伯轉換,短時傅立葉轉,希爾伯特黃轉換

 

4. 分數傅立葉轉換 及 線性完整轉換

  簡而言之,分數傅立葉轉換是做零點幾次的傅立葉轉換,分數傅立葉轉換是傅立葉轉換的一般化,線性完整轉換是分數傅立葉轉換的進一步一般化,這些都是先進的信號處理技術

5. 小波轉換

6. 音樂及聲音信號處理

7. 快速演算法

8. 整數轉換 

   以設計出不需浮點運算,且適合於低成本的硬體的演算法為目標

9. 生物資訊學

   用信號處理的方法處理基因比對的問題

10. 信號分析
  包括心電圖分析, 數論,分碼多重存取,特徵函數與扁平波函數的問題 

11. 其他
   包括四元素,非線性及時變系統分析數位濾波器設計

Research Summary:

1. Digital Image Processing 

     including pattern recognition, image deblurring, saliency detection, corner and edge detection, watermark and encryption

2. Image Compression  

 

3. Time-Frequency Analysis

      including Wigner distribution functions, Gabor transforms, short-time Fourier transforms, Hilbert-Huang transforms

 

4. Fractional Fourier Transform and Linear Canonical Transform

      In a word, the fractional Fourier transform is doing the Fourier transform x times where x can be non-integer. Fractional Fourier transform is a generalization of the Fourier transform. Linear canonical transform is a further generalization of the fractional Fourier transform. These are advanced digital signal processing techniques.

 

5. Wavelet Transform

6. Music and Acoustics

7. Fast Algorithm

8. Integer Transform

    the goal is to develop the operations that needs no floating-point processor and are suitable for low-cost hardware implemetation 

9. Bioinformatics

    using the method of signal processing for DNA sequence comparison

10. Signal Analysis

     including eigenfunctions and prolate spheroidal wave function, CDMA, number theory

11Others

      including ECG signal analysis, quaternion, non-linear and time-variant system analysis, digital filter design
