Hello
I would like to calculate a weighted line integral.
The integral is calculated by the cells that this lines trasverses (the small
cells belong to matrix (m*n) that represent the value that a specific area has.
I need to calculate the weights by finding out how much the line touches or
impinges inside a cell.
The weight is less if a line just touches one of the four edges of a square and
much more if it traverses inside the cell. I think there might be some function
to calculate this in any image processing packages.
So far I could not find anything appropriate.
Could you please help me with that?
I would like to thank you in advance for your help
Best Regards
Alex
