1. Forward Rotation: Write code to perform forward rotation on an image. o Starter code available in directory Tranform/ o Transform/geometric.py: Edit the function forward_rotate to implement this

2.Reverse Rotation: Write code to perform reverse rotation on the input image. o Starter code available in directory Tranform/ o Transform/geometric.py: Edit the function reverse_rotation to implement this

3.Rotation with interpolation: Write code to rotate an the input image, using nearest neighbor and bilinear interpolation. o Starter code available in directory Tranform/ o Transform/geometric.py: Edit the function rotate to implement this part. o Transform/interpolation.py: Write code for linear and bilinear interpolation in there respective function definitions, you are welcome to write new functions and call them from these functions

The assignment can be run using dip_hw1_rotate.py (there is no need to edit this file) Usage: ./dip_hw1_rotate.py -i image-name -t theta -m method o image-name: name of the image o theta: angle in radians to rotate the image (eg. 0.5) o method: "nearest_neightbor" or "bilinear" Please make sure your code runs when you run the above command from prompt/Terminal

Any output images or files must be saved to "output/" folder One images is provided for testing: cameraman.jpg

Notes:

1. Files not to be changed: requirements.txt and Jenkinsfile

2. the code has to run using one of the following commands

Usage: ./dip_hw1_rotate.py -i image-name -t theta -m method Example: ./dip_hw1_rotate.py -i cameraman.jpg -t 0.5 -m nearest_neighbor

Usage: python dip_hw1_rotate.py -i image-name -t theta -m method Example: python dip_hw1_rotate.py -i cameraman.jpg -t 0.5 -m bilinear

3. Any output file or image should be written to output/ folder

4. The code has to run on jenkins CI/CD

5. Do not use any in-built functions from opencv and numpy (E.g: np.mean). In general, you can use functions from the math (sin, cos, etc) library.

6. The only allowed functions for this part are: np.array(), np.matrix(
