Crop all written letters from single image 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
Presumably this is an academic assignment of some sort and you are expected to use a specific tool, OpenCV I am guessing. You should review the documentation for that tool and try to find a feature which matches the requirements. I suspect you would need to use the Image Segmentation feature: https://docs.opencv.org/3.4.3/d3/db4/tutorial_py_watershed.html
