6. Team Project Checkpoint 2
In this module, you will implement edge detection using a Sobel filter. You will then use these techniques along with the functions from the previous checkpoint to extract features from images, scale the feature dataset, and visualize the results.
Topics Covered
Implementing Sobel filter with thresholding for edge detection
Extracting image features and building a feature dataset
Using pandas for data manipulation and analysis
Feature scaling and labeled scatter plot visualization
Learning Objectives and Course Outcomes
At the end of this module, you will be able to:
Isolate edges of objects within an image using a Sobel filter
Extract image features and build a feature dataset
Scale a feature dataset and create a labeled scatter plot
Write Python code that adheres to professional programming standards
These learning objectives are directly connected to the following Course Outcomes:
- CO 1.1:
Visually represent data and derive meaningful information from
data.
- CO 2.1:
Contribute to team products and discussions.
- CO 3.1:
Communicate engineering concepts, ideas and decisions effectively
and professionally in diverse ways such as written, visual and oral.
- CO 4.1:
Develop code solutions that address engineering questions and
follow professional programming standards.
- CO 4.2:
Understand and implement basic and intermediate programming
structures: sequential structures, selection structures, repetition
structures, and nested structures.
- CO 4.3:
Create adaptable, reusable programming routines.
- CO 4.4:
Apply design ideas to programming solutions.
