Match Single Image with Read-Only Directory

[ashish128]

Dear Developer,

Am a noob but still love programming (have just started) so excuse me if anything below is "obvious" or "incorrectly stated".

I got the gist that this will match all files in the given directory for similarity.

First Point: Is it possible to match an image (file path to pass as parameter) against a directory path (folder path to pass as parameter)? Which Means that instead of Matching all Images against all images, we could match just one image against all images of a folder.

Second Point: Is the function writing something in the Search folder (like tensor Data or anything)? Am asking to understand if this can work in read-only directory or not. (I tried reading the code but could not figure it out)

Third point: If we have to run / call it multiple times on a large folder then would it be taking long time analyzing all files each time or is it possible to provide / pass a path to file / folder where it can save the analysis to save the time?

Example: (No text in below lines is crossed so please do not ignore if any text is coming crossed. I could not figure out why is it applying this formatting")

Input_file_path = "/Downloads/image.jpg" # Any valid Image File
Target_Folder_path = "/A_Readonly_Folder_of_Images" # A Read-only folder with say 56,000 (big number ?) files to search from.
Working_File_or_Folder_path: "~/A_File_or_Folder_with_Read_Write_Access" # A Write access enabled file / folder to save analysis data to / from.
E.g.
If the passed parameter file / folder does not exist then create one and save analysis data.
If the passed parameter file / folder does exist then read it and use it instead of analyzing the Target Folder again
#calling
dif.compare_image(Input_file_path,Target_folder_path,Working_Folder_path)

Please excuse me if am crossing any limits here. I just became curious about this wonderful concept but I know nothing about github and how it works.

Best Regards
Ashish

Agree with the first point. A use case for me is:

Directory1: Thousands of non-duplicate images
Directory2: Single, or few images that may be a duplicate of the contents in Directory1

Right now I have to move the single or few possible duplicates from Directory2 into Directory1 and run difPy. The problem is, of course, that difPy compares all of the known-unique images in Directory1 with the other known unique images, thus wasting computation cycles. Would love to see this functionality added!

Dear Ashish,

Thank you for your input! Please find below a few comments from my side:

First Point: unfortunately, as of v2.0 it is not possible to pass the location of one specific file as a parameter to the function. For the moment, only folder paths are supported, meaning your single image must be located in a folder itself. This is a feature that will be considered for future updates, thank you!

Second Point: the function does not write or save any data into the folders, therefore it will also run on read-only directories. I also tested this myself and can confirm.

Third point: unfortunately, as of v2.0 difPy does not provide any option to store the computed data and reuse it ls. This is a feature that might be considered for future updates, thank you!

All the best,
Elise

Dear snoozesecurity,
This issue has been addressed in the new version v2.0 of the difPy.
Thanks a lot for your input!
