Crop all written letters from image to form a website

Question

• Above image has handwritten hindi / deavanagari letters all on a single

  image.

• Task is to Prepare a dataset from the given assignment.jpg image using image

  processing tools

• Idon't have clarity whether i can use photoshop editing tools like adobe photoshop etc.

• If image processing tools mean opencv , is it really possible to create like a emnist like dataset from single image.

• I am not able to come up with any way to seperate the letters from eachother

Finally i had done it by combining adaptive thresholding,bluring,and morphological, It is helpful to check out find contours for two part letters by @Salman and @Jeru Luke , it really helped me.
