1 Face Detection in the Wild (8 Points)
The goal of this project is to have you utilize the face detection algorithms available in opencv library (preferably opencv version>4.0).
1.1 Project Description
Given a face detection dataset composed of hundreds of images, the goal is to detect faces contained in the images. The detector should be able to locate all the faces in any testing image. Figure 1 shows an example of performing face detection. We will use a subset of FDDB [1] as the dataset for this project. You can use any face detection modules available in OpenCV.
Figure 1: An example of performing face detection. The detected faces are annotated using gray bounding boxes.
1.2 Libraries permitted and prohibited
- Any API provided by OpenCV.
1.3 Data and Evaluation
You will be given 100 images along with ground-truth annotations (validation folder). You can evaluate your model performance on this validation set or use it to further improve your detection.
1
During testing, you need report results on another 100 images (test folder) without ground truth annotations.
The following shell 代做 script代写”> bash script will be used to evaluate the performance of the face detector you created:
unzip FaceDetection.zip cd [FaceDetection] python3 FaceDetector.py [data-directory] python3 ComputeFBeta.py ./results.json [ground-truth.json]
FaceDetector.pycontains YOUR Python code that will able to detect faces in all the images in [data-directory]and generate a json file,i.e.,results.json, that stores all the bounding boxes of the detected faces. The generated json file shall be located in the same folder where the images are located. The bounding boxes of the detected faces should be stored in a list using the following format:
[{"iname": "img.jpg", "bbox": [x, y, width, height]}, …]
"img.jpg"is an example of the name of an image;xandyare the row index and column index of the top-left corner of the bounding box; widthandheightare the width and height of the bounding box, respectively.x,y,widthandheightshould be integers.
We will provideComputeFBeta.py, a python code that computesf usingresults.jsonand the ground truth in[ground-truth.json].
You can refer to the sample json provided to you for more information. There is also a piece of example code regarding how to create json file.
1.4 Evaluation Rubric
We will be awarding 5 points for F1 score computed, 1 point for code and 2 points for report. For F1 score computed using ComputeFBeta.py. (5 points)
- F1>0.5: 5 points
- F1>0.35: 4 points
- F1>0.2: 3 points
- F1>0.05: 2 points
- F1:>0.01: 1 points
- F1:<0.01: 0 points
Code:
- Submitted code is reasonable and interpretable (1 point)
Report:
- Concise description of your implementation (1 point)
- Discussion of the results and and implementation issues (1 point)
1.5 Code and Report
Submission package requirements:
As shown in 1.5, please create a FaceDetection.zip accordingly. Since this project allows more flexibility in the use of libraries, please also remember to include a file with your resources your code requires to make it easier on the grader. This should be in the form of a txt file named requirements.txt. The file named requirements.txt should specify the libraries you used and the version of the libraries, and our grader should be able to install all the libraries you used by using the command: pip install -r requirements.txt
In addition to your code, a report is required with this project. It should contain
- Your name and your UBID.
- A description of your implementation,
The report should be a pdf file. You will be graded based on the report, code and an evaluation on the 100 images in test folder. You only need to upload the results.json in the test folder and do not need to upload any image results during submission.
2 K-means Clustering (7 points)
X=
5 .9 3. 2
4 .6 2. 9
6 .2 2. 8
4 .7 3. 2
5 .5 4. 2
5 .0 3. 0
4 .9 3. 1
6 .7 3. 1
5 .1 3. 8
6 .0 3. 0
Given the matrixX whose rows represent different data points, you are asked to perform a k-means clustering on this dataset using the Euclidean distance as the distance function. Here k is chosen as 3. All data inXwere plotted in above Figure. The centers of 3 clusters were initialized as 1 = (6. 2 , 3 .2) (red), 2 = (6. 6 , 3 .7) (green), 3 = (6. 5 , 3 .0) (blue). Implement the k-means clustering algorithm(you are only allowed to use the basic numpy routines to implement the algorithm).
- ClassifyN= 10 samples according to nearesti(i= 1, 2 ,3). Plot the results by coloring the empty triangles in red, blue or green. Include the classification vector and the classification plot ( task2iter1a.jpg) in the report. (1 point )
Hint: Usingplt.scatter with edgecolor, facecolor, marker and plt.text to plot the
figure.
- Recomputei. Plot the updatediin solid circle in red, blue, and green respectively. Include the updated values and the plot in the report ( task2iter1b.jpg) (1 point).
- For a second iteration, plot the classification plot and updatediplot for the second iteration. Include the classification vector and updatedivalues and these two plots (task2iter2a.jpg, task2iter2b.jpg) in the report. (1 point)
Figure 2: baboon.png
- Color Quantization(4 points) Apply k-means to image color quantization. Using only k col- ors to represent the image baboon.png(shown in Figure. 2). Include the color quantized im- ages fork= 3, 5 , 10 ,20 (task2baboon3.jpg, task2baboon5.jpg, task2baboon10.jpg, task2baboon20.jpg ). Note : Place the code and report in k-means.zip folder.
3 Submission Guidelines
- Unlimited number of submissions is allowed and only the latest submission will be used for grading. Add FaceDetection.zip and k-means.zip into a folder and create UBIDproject3.zip. Please upload this to UBlearns.
- Not following submission guidelines strictly will result in large penalty.
- Identical code will be treated as plagiarism. Please work it out independently.
- For codes raising RuntimeError, the grade will be 0 for this task.
- Late submissions within 24 hours are allowed and will result in a 40% penalty. After one day, submissions will not be accepted.
