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.
