extract_image_data (Images2CSV)

Fast multithreaded script for converting a large number of images to CSV data

Usage

$ python extract_image_data.py <input_folder_path> <output_csv_path>

Requirements

Install the requirements by calling pip on the requirements.txt file

$ pip install -r requirements.txt

Example

$ python extract_image_data.py images data.csv

How it works

Converts all images within input_folder_path into a CSV file located in output_csv_path.

• The filename of the image (without the extension) is stored in the first column.

• The shape of the image data is stored in the second column.

  • For black and white images, rank = 2.

  • For colored ones, rank = 3 where the data is a matrix of RGB lists.

• Subsequent columns are the feature columns that encode color of each pixel.

Multithreading

There will be n_cores number of threads, where n_cores is the number of cores in the CPU where the script is being run.
