Sample Assignment


CLab-2 Tasks


Task 1 Harris Corner Detector. (6 marks)

For Matlab Users:


1. Read and understand the corner detection code ‘harris.m’ in Fig 1.


2. Complete the missing parts, rewrite ‘harris.m’ into a Matlab function, and design appropriate function signature (1 mark).


3. Please provide comments on line #13 and every line of your solution after line #20 (0.5 mark). Specifically, you need to provide short comments on your code, which should make your code readable.


4. Test this function on the provided four test images (Harris-[1,2,3,4].jpg, they can be downloaded from Wattle). Display your results by marking the detected corners on the input images (using circles or crosses, etc) (0.5 mark for each image, (2 marks) in total).

Please make sure that your code can be run successfully on a local machine and generate results. If your submitted code cannot replicate your results, you may need to explain and demonstrate the results in person to tutors.

In your Lab Report, you need to list your complete source code with detailed comments and show corner detection results and their comparisons for each of the test images.


6. Test your built function on ‘Harris-5.jpg’ (Harris-5.jpg can be downloaded from wattle.). Analyse the results why we cannot get corners by discussing and visualising your corner response scores of the image. (0.5mark)


7. Test your built function on ‘Harris-6.jpg’ (Harris-6.jpg can be downloaded from wattle.). Plot your harris corner detector results in your report and propose a solution to obtain the salient corners which is robust to noise. (0.5mark)


For Python users:

1. Read and understand the above corner detection code (Fig. 2).


2. Complete the missing parts, rewrite them to ‘harris.py’ as a python script, and design appropriate function signature (1 mark).


3. Comment on block #5 in the python file (which is corresponding to line #13 in “harris.m”) and every line of your solution in block #7 (0.5 mark). Specifically, you need to provide short comments on your code, which should make your code readable.


4. Test this function on the provided four test images (Harris-[1,2,3,4].jpg, they can be downloaded from Wattle). Display your results by marking the detected corners on the input images (using circles or crosses, etc) (0.5 mark for each image, 2 marks in total).


Please make sure that your code can be run successfully on a local machine and generate results. If your submitted code cannot replicate your results, you may need to explain and demonstrate the results in person to tutors.


5. Compare your results with that from python’s built-in function cv2.cornerHarris() (0.5 mark), and discuss the factors that affect the performance of Harris corner detection (1 mark).


6. Test your built function on ‘Harris-5.jpg’ (Harris-5.jpg can be downloaded from wattle.). Analyse the results why we cannot get corners by discussing and visualising your corner response scores of the image. (0.5mark)

Plot your harris corner detector results in your report and propose a solution to obtain the salient corners which is robust to noise. (0.5mark) In your Lab Report, you need to list your complete source code with detailed comments and show corner detection results and their comparisons for each of the test images.


Task 2 - Deep Learning Classification (10 Marks)


In this lab, we will train a CNN with the Fashion-MNIST using the PyTorch1 deep learning framework. The Fashion-MNIST dataset contains 70000 images: 60000 training images and validation images, 10000 testing images2 for fashion classification task. Note that we have 60000 training images with labels. You are required to split the 60k training data further by yourself to reserve 1000 images for validation (they should be from 10 classes). Images are of size 28×28 Greyscale, for 10 classes:


Label Description

0 T-shirt/top

1 Trouser

2 Pullover

3 Dress

4 Coat

5 Sandal

6 Shirt

7 Sneaker

8 Bag

9 Ankle boot


Complete the following exercises:

1. Download the Fashion-MNIST dataset from the following git link: link

1Let tutor know if you want to use tensorflow which is acceptable.

2The reference for the dataset is: Han Xiao, Kashif Rasul, and Roland Vollgraf. "Fashion-mnist: a novel image dataset for benchmarking machine learning algorithms." arXiv preprint arXiv:1708.07747, 2017. 3


2. After loading the data using numpy, normalize the data to the range between (-1, 1). Also perform the following data augmentation when training:

  • randomly flip the image left and right.

  • zero-pad 4 pixels on each side of the input image and randomly crop 28x28 as input to the network.


3. Build a CNN with the following architecture:

• 5×5 Convolutional Layer with 32 filters, stride 1 and padding 2.

• ReLU Activation Layer.

• 2×2 Max Pooling Layer with a stride of 2.

• 3×3 Convolutional Layer with 64 filters, stride 1 and padding 1.

6. Train your model.


Draw the following plots:

  • Training loss vs. epochs.

  • Training accuracy vs. epochs.

  • Validation loss vs. epochs.

  • Validation accuracy vs. epochs.


You can either use Tensorboard to draw the plots or you can save the data (e.g. in a dictionary) then use Matplotlib to plot the curve. (2 marks)


7. Train a good model. Marks will be awarded for high performance and high efficiency in training time and parameters (there may be a trade-off), good design, and your discussion.


You are not allowed to use a pre-trained model, you should train the model yourself. You need to describe what exactly you did to the base model to improve your results in your report, and your motivation for your approach (no more that 1 page of text). Please include plots as above for training and validation loss and accuracy vs. epochs, as well as the final accuracy on the test set. Please submit the code and your trained model for this. Your performance will be verified. Please ensure you follow the test/train splits as provided. You also must show your training and validation accuracy vs. epochs for this model in your report.

Note that you may be asked to run training of your model to demonstrate its training and performance. (4 marks)


8. The main dataset site on github (https://github.com/zalandoresearch/fashion-mnist) includes a series of results for other network models (under Benchmark). How does your model compare? Explain why the ResNet18 model may produce better results than yours (or the other way around if this is the case).(1 mark).

In your Lab Report, you need to list your complete source code with detailed comments.
