Script to randomly select some of the extracted frames

[stathdim]

This script should utilize the frames naming pattern (string+number.jpg) to make selection easier.
We can simple generate a random number from 1 till (number of frames) and select the corresponding frame. Afterwards the generated number is stored in a selected_frames list. Then for each number we generate we check if the frame was already selected

Create random frame selection script

import os

os.chdir('videos/')

def readFilenames(): 
    files = set()
    with os.scandir('.') as entries:
        for entry in entries:
            filename = entry.name.split('.')[0]
            files.add(filename)
    return files

# Each filename must be unique to avoid processing the same file twice
files = readFilenames()

# Read all files and strip the extension 
# We use just the filename title to avoid having to if-else about the extensions
with os.scandir('.') as entries:
    for entry in entries:
        filename = entry.name.split('.')[0]
        files.add(filename)

The code above is can be used as a blueprint for reading the images from the filesystem
