                Week 3: IR Image Processing & Preliminary MAT- LAB Code


14/02/2025

Summary of Activities

1.    IR Image Analysis

•  Finally received a few infrared images (e.g., “IR 00345.jpg”) and tested our Gas- Tube boundary detection script.

•  Implemented Gaussian smoothing, contrast enhancement, and Otsu thresholding to isolate key regions (the gas tube).

2.    Segmentation Approaches

•  Explored both threshold-based segmentation and Canny edge detection.

•  Found that morphological operations (imclose, imopen, imfill) were critical to suppress noise and highlight main object boundaries.


3.    Code Organization

•  Consolidated our functions into single MATLAB scripts or Live Scripts. Added thorough inline comments and verified toolbox requirements.



Challenges/Concerns

•  MATLAB Toolbox Dependence: Needed the Image Processing Toolbox on each team member’s workstation.

•  Variation in IR Quality: Different brightness and noise levels required re-tuning parameters.

•  Transition to Gravestones: We would soon apply the pipeline to gravestone images, which may require additional alignment if IR and visual versions exist.
