國立台灣大學電機工程學系 教授
Professor, Department of Electrical Engineering, National Taiwan University
Professor,Graduate Institute of Communication Engineering, National Taiwan University

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, image segmentation, corner and edge detection, watermark and encryption

2. Image Compression  

    including entropy coding, still image and video compression, multimedia compression techniques

3. Time-Frequency Analysis

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

4. Artificial Intelligence and Machine Learning

    including theories of machine learning and their applications in face detection, expression recognition, and object recognition

5. 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. The fractional Fourier transform is a generalization of the Fourier transform. The linear canonical transform is a further generalization of the fractional Fourier transform. These are advanced digital signal processing techniques.

6. Music and Acoustics

    including query by humming, denosing for vocal signals, voiceprint analysis 

7. Wavelet Transform

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
