In a hyperspectral imaging, we have more than 100s bands. I want to select best feature wavelength to classify the fruits based on the injury level. How to proceed on this?
Use the highlighter tool and mark the areas with injury with that.
When you will mark it then the wavelength section will be shown.
Repeat this multiple times to see the optimum range.
Shubhangi Srivastava The injury is internal injury (cold injury) and not visible from outside. Even though I see so many bands are showing the difference, I want to select only few bands with highest accuracy. Say five best band out of 140 band that give the best classification accuracy. How to say which five bands are best ones?
Then you can do I thing
Let say you want five bands
Then take 3 bands with maximum variance and 2 bands with median values.
This will help as it will take into consideration
1.every focal point of injury.
2. Median values will help to focus on inured tissues more.
But before doing so make sure to eliminate background effects with help of a tool.
