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:

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
