Including Image transformation, Image enhancement, Image restoration, Segmentation

1. Image transformation, DFT, DCT

a. Open and show a file with different file extensions.(BMP/JPG/GIF/TIF/PNG,etc)

b. DFT, IDFT and their spectrums

c. DCT, IDCT and their spectrums

2. Image enhancement: Gray-scale transformation, Histogram, Histogram equalization, Histogram specification, Spatial smoothing, Spatial sharpening

a.	Gray-scale transformation:reverse, piecewise linear transformation, logarithmic transformation, etc

b.	Gray histogram

c.	Histogram equalization;

d.	Histogram specification: shape of traget histogram is equal to a Isosceles triangle

e.	Spatial smoothing: offer differents smoothing filters, such as median filter, mean filter, etc

f.	Spatial sharpening: offer differents sharpening filters, such as Robert, Sobel, etc

3. Image enhancement: Low-pass filtering, High-pass filter

a.	High-pass filter: ideal // Butterworth // Gaussian low-pass filter

b.	Low-pass filtering: ideal // Butterworth // Gaussian high-pass filter

4. Image restoration by using inverse filter

5. Segmentation

a.	 Human segmentation: threshold, edge detection and region based methods

b.	 Face recognition

c.	 Save and label the results of 5.a and 5.b

d.	Face segmentation: obtain and save different regions of forehead, cheeks, nose and chin
