hi, i need help to write a more specific algorithm for a section of
my code, hopeing someone can help...stick with me here...
i have about 4000 rows, and 3 coloumns in a matrix.
i also have a number value the user inputs called n
the values in the 1st and 2nd coloumn are x and y coordinates of the
value in the 3rd coloumn (which is a pixel intensity value).
some of the values (intensity) in the 3rd coloumn is -1.
here it is....
i need to go through every row in the 3rd coloumn untill i come
across a -1 (which i have done)...then...
find 'n' number of values in the 3rd coloumn NOT equal to -1, that
are positioned NEAREST to the -1 i have found, and return their
intensity values....
hope someone can help....thanks....Marley
