Hello everyone,
I want to build a simple app in MIT App Inventor for groundnut kernel analysis.
Requirement:
Point mobile camera to peanut kernels spread on a table
App should count the number of kernels visible automaticly
Any extension availabe ?
Thanks in advance for your help!
not simple
A possible extension method but it is NOT free. 
**Using Blocks (free) **
Here is a discussion about using Blocks and the camera to estimate number, size and distance between objects that you might find the number of objects in a photo. It won't count automatically but it might provide some ideas for you to adapt.
