[Learning][Core] Add more step-wise output images for intuitive understanding

[Udayraj123]

Best part of working with opencv is visually seeing each step. OMRChecker provides a way to see the step-wise images. But they have a scope to improve.

Steps

1. Learn about existing step-wise images that OMRchecker generates (set show_image_level to 4 or 5)
2. Propose and discuss which images can be added to the steps for intuitive understanding of the process.

Can I try this issue?

[Udayraj123]

@infinity1729 sure. Let me know if you need any help. Do share what you've done till now (setup, running samples etc)

head on to discord for discussing in hacktoberfest channel.

I made following observations:

• If show_image_level is 1 and any value of save_image_level which is greater than 3, the output stack would include max 3 stacks.
• save_image_level values >=5 saves only stack 1,2,3,5. (i.e. stack 4 is missing)
• Executing code with save_image_level lesser than it's previous values (say save_image_level=5 then save_image_level=3) keeps the extra stacks of previous iterations which is undesirable.

I'll be working on the following tasks

• Debugging above observations.
• Plugins that pass save_image_level as a parameter.

@infinity1729 let me know once you have any update

Sure, currently working on issue #88

One more potential output can be the pipeline visualisation in ImagePlay
