Description
Session Goal
The session aimed to develop a comprehensive image processing and analysis pipeline using Python, focusing on retrieving image file paths, performing face detection, and analyzing image metrics.
Key Activities
- Image File Path Retrieval: Implemented code to import necessary libraries and retrieve sorted paths of JPEG images from a specified directory.
- Image Counting: Retrieved and counted image file paths using libraries like glob, numpy, and pandas.
- Face Detection: Set up a face detector with OpenCV and defined functions to compute metrics such as blur, brightness, contrast, and face detection statistics.
- Data Normalization and Scoring: Normalized specific columns in a DataFrame and calculated a composite score based on weighted factors for face analysis.
- DataFrame Analysis: Sorted and analyzed DataFrame columns, providing unique value counts for ‘faces’ and sorting by the ‘score’ column.
Achievements
- Successfully retrieved and processed image file paths.
- Implemented face detection and metric calculation using OpenCV.
- Normalized data and calculated composite scores for enhanced analysis.
Pending Tasks
- Further optimization of the image processing pipeline for performance improvements.
- Integration of additional image metrics for comprehensive analysis.
