What are we doing in this blog?

We are changing folders name like this:

Folder Name from n02113023-Pembroke Changed to Pembroke
Folder Name from n02113624-toy_poodle Changed to Toy Poodle
Folder Name from n02115641-dingo Changed to Dingo

If want to learn this, Go on with reading:

In this, dataset directory. I have downloaded, famous standford dataset. The Stanford Dogs dataset contains images of 120 breeds of dogs from around the world. This dataset has been built using images and annotation from ImageNet for the task of fine-grained image categorization.

The name of the folders (which will be used as classes while training) have names like, n02093256-Staffordshire_bullterrier. We definitely don’t want our class to be like that but rather simple Staffordshire Bullterrier. The python script will get rid of any weird characters that are unneccessary.

Now, we have our path defined where the data is situated. In my case, i had uploaded it to google drive. Time consuming upload, avoid it if possible.

Let’s say we have folder name like this:

n02093256-Staffordshire_bullterrier

Here is our process of obtaining what we want,

We first split on the basis of - (hyphen) charachter
Then we obtain list like this: ['n02093256' , 'Staffordshire_bullterrier']
After that, we use slicing technique to select second index.
Then after we have what we wanted, we can simply again split on the basis of _ (underscore)
Then we obtain something like this: ['Staffordshire','bullterrier']
After we have what we wanted we can simply join the list back. And use capitalize to make first letter of word capitalize.

📝 Note: This code will need to be modified according to the folder name you are dealing with.

    return string.capwords(folder_name) #or we can use capitalize()

#iterating over all the folders and changing file name
