Hello friends of MRL!  surprise

Today I went to my college and I performed some tests with vegetation seeking identification of crops or trails that future tractors with computer vision equipment can be applied ...

My camera: (Logitech C270 + Nikon coolpix L120)

 

 

Test 1 -Identification of the track or road just ignoring the vegetation around ... was not very good will need to apply filters or other identification techniques that improve or enhance the road:

I'm using PyramidDown Filter and InRange Filter:

 

InRange with this configuration: 

 

Obs: I dont liked of the result..  and after i have other tests:

 

Test 2 - In this second test I applied the same filter and also a FinContour and ended up having a better result:
 
 
InRange configuratiosn:
 
 
In this test I applied FindContours filter which helps in identifying the object or space. Got a little better .. As I walked to her identified ...
 
 
Test 3 - Identification of yellow flowers .. i loved this test.. work fine
 
 
 
Here I used three filters mentioned previously (PyramidDown, InRange and FindContour) ... 
 
 
Now I have a question .. There are other ways to enhance or improve this recognition? 
Can I apply more filters together to improve this application? 
Thank you! :)

Great Post Saymon !  You've taken MRL outside ! 

I like that you showed the values of the InRange filter as part of the post.

To your question, yes .. there is always more ways to improve...
The first image might benefit from a filter not created yet which uses a sample at the lower edge of the picture.  It uses this sample to match in color & possibly texture.   This would be a "FloorFinder" filter - it would allow you not to have to do the ranging yourself.  Because it would use the sample to do this.

Same goes for the second picture.  Additionally since there are very visible lines you could use HougeLines possibly to find the path.

The last one might benefit from a template match filter, but it would require your current filter to save the "squares" of data off to be recognized later.  

I hope you continue to do interesting experiments !

The Nikon coolpix doesn't do streaming, does it ?  The pictures you posted are from both cameras or just the Logitec ?

Man this is cool. Monitoring wear and tear on trails and deseetification is really exciting.
