Hello,
i want to count grains of and in cereal plant with the help of a camera. I already tried methods like watershed or edge detection to seperate the grains but without success. Maybe someone of you has ideas or advice on how to better solve this problem?
Interesting problem. Did you check some articles in this field for ideas?
Anyway, counting individual grains (image 1) will probably give better results, as in kernels (image 2) you can't see all the grains (half of them are masked.
Based on my experience, it's better to work on the image acquisition conditions (especially lighting), it will make further work much easier.
For example you could put the grains on an opaque glass and provide a back light; expose for the background light, so the grains remain black over a white background in the image.
Then threshold the image and count the local maxima of the distance transform.
This is especially true for agriculture-related applications - and it's even worse for images acquired in the field (outside).
The objects to detect are very diverse, the environment is complicated and the lighting conditions are catastrophic... you rather think first how to take images that will be easier to process.
Generally a well thought lighting can really help a lot!
