Refine image after remove the green background should be more clear #73

Closed nmedia82 closed 2 years ago

nmedia82 commented 2 years ago

Chroma Green Python script Thanks for the great set of tutorials. Actually, the file processed image is not very clear it has some green edges. Do you know how to refine the script to remove these tiny green edges?

Hello! Great to hear you enjoyed the tutorials!

The Chromakey function (https://github.com/aws-samples/aws-serverless-workshop-innovator-island/blob/main/3-photos/1-chromakey/app.py) take two environment variables specifying the lower and upper bounds for HSV values. These help isolate the green shades:

HSV_LOWER: A tuple representing lower HSV value for the green screen chroma key matching process. HSV_UPPER: A tuple representing upper HSV value for the green screen chroma key matching process.

By experimenting with the first value in each tuple (i.e. lower than 36 and more than 75), you can finetune the chromakey process. I hope this helps!
