4. Introduction
Tea leaf:
Tea is an aromatic beverage commonly prepared by
pouring hot or boiling water over cured leaves.
Cultivation In Bangladesh :
BT-2 & BT-30
Climate Change
Image processing by using MATLAB.
Better Liquor Factor for better tea.

8. Collect images from tea garden
Resize the images of tea leaf
Give color tea leaf image as input.
Convert it into color spaces
Apply mathematical operation
Find entropy and liquor factor for mathematical operation
Compare among the liquor factor of elder leaf, tender leaf, perfect leaf .
Finally estimate the liquor content in tea leaf.

34. The capacity of liquor content by perfect leaf is highest as a
result we can say that perfect leaf prefer more liquor than
elder and tender leaf. We find out the highest liquor factor is
0.0022 from perfect leaf, and it is suitable for better tea liquor.
