Description

Homework Assignment #1
Requirement
1. Write a program for non-integer scaling of an image with two options:
— Bilinear interpolation
— Bicubic interpolation
2. Take a selfie of yourself, and apply the above image scaling program on your selfie (or part of your selfie, e.g., your right eye) with the scaling factors of 0.3, 3.0 and 18.
3. Compare the quality of the images obtained with bilinear interpolation and with bicubic interpolation.
4. Explain the method of bicubic interpolation, and compare its complexity with bilinear interpolation.
Language for Implementation
• C, C++, Python, JAVA or Matlab
(If you want to use other languages, please contact
TAs. We need to make sure we can run your program!)
• openCV is a useful open library for image processing

• For requirement 3, 4, you need to provide
• Result images for comparison
• Explanation
Submission
• Please submit a .zip/.rar file to ceiba, containing
• Project(source code and execution file)
• Report(.pdf file) • Late submission:
Note: One minute late is the same as 23 hours late.
