This course is an elective. It introduces the fundamentals of image and video processing to seniors and has two dual goals: (1) provide students with a broad set of skills in this rapidly growing area, and (2) prepare students for further in-depth study of this field.

A. By the time of Exam No.1 (after 10 lectures), the students should be able to do the following:

1. Compute a two-dimensional (2-D) Fourier transform in both discrete and continuous spatial coordinates, and implement the 2-D discrete Fourier transform. (a,b,k,m)

2. Identify an appropriate sampling resolution, given the 2-D spectrum of a continuous image. (a,b,k,m)

3. Perform 2-D finite-impulse-response (FIR) filtering of images. (a,b,k,m)

4. Design 2-D decimation and interpolation schemes. (a,b,k,m)

5. Understand basic properties of the human visual system. (a,b,c,k,m)

6. Quantitatively evaluate image quality based on Frei and Baxter?s color vision model. (a,b,c,k,m)

7. Determine appropriate specifications for a charge-coupled-device (CCD) camera. (a,b,c,e,k,m)

8. Determine appropriate specifications for the amplitude and spatial resolutions of an image display system based on the characteristics of the images and the contrast sensitivity and spatio-temporal modulation transfer function of the human visual system. (a,b,c,e,h,i,k,m)

9. Design appropriate specifications for a color quantization system based on the color vision properties of the human visual system. (a,b,c,e,h,i,k,m)

11. Perform halftoning and error diffusion operations. (a,b,c,e,k,m)

B. By the time of Exam No.2 (after 20 lectures), the students should be able to do all of the items listed under A, plus the following:

1. Know basic features of digital video standards for high-definition television (HDTV), standard-definition television (SDTV), videoconferencing (CIF) and videophones (QCIF). (a,b,c,e,f,h,i,j,k,m)

2. Select an appropriate format for various video applications. (a,b,c,e,h,i,j,k,m)

3. Design a point operation to improve contrast or modify the dynamic range of grayscale and color images. (a,b,c,e,h,i,j,k,m)

4. Perform histogram equalization and histogram specification on an image. (a,b,c,e,h,i,j,k,m)

5. Design an edge-enhancing linear filter. (a,b,c,e,h,i,j,k,m)

6. Design low-pass and median filters for reducing the noise level in an image without drastically affecting image contents, and select an appropriate filter depending on noise characteristics. (a,b,c,e,h,i,j,k,l,m)
