What method to check the properties of files and the quality of pictures in large quantities?

Question

JPEG

Good afternoon! The essence of the task: to audit the quality of images for products, and this is over 40k files.
I want to get a list of files that have dimensions less than 200x200px, image weight greater than 2M, or number of dots less than 4px.
You need to find out which files are of low quality and which are of high quality and get a list with parameters.
How to approach this task? Write something in C or is it possible through .bat?

Answer 1

Download the powershell script.
For example, with this script I collect music over 1 megabyte in order to discard skits and small intros.

"Собираем информацию обо всех mp3 файлах в указанной папке и её подпапках... Ждите..."
    $save = Get-ChildItem -Recurse -LiteralPath $sourceDirectory | where{$_.extension -eq '.mp3'}

    $res = 0..$save.Length

    for( $i = 0; $i -lt $save.Length; $i++ )
    {
    if( ($save[$i].length / 1MB) -gt 1 )
    {
      $res[$i] = $save[$i].fullname
      Out-File -FilePath "random_music_data.txt" -InputObject $res[$i] -Append
    }
    }

You will need to get the "picture" object and look at the resolution, in addition to the size. Google it.)
