Segment color patch from test chart and compute RGB/L*a*b* values of each color patch

1 view (last 30 days)
I was trying to scan a test chart and write a code that would automatically segment each color patch without me manually cropping them. The intention is to calculate the RGB/L*a*b* values for each of the patches in the chart. Pls help.

You can use deltaE metric and colors that have distances less than 2 can be grouped together.
