I am working to Gray-scale image files(TIFF) , I
need to calculate the Orientiation of the Pixels , for
that I need to calculate Directional Filed Estimation.
For Directional Field Estimation I need to fined the
Gradient.
Gradient can be calculated by Partial Differentiation.
Can you help me out to calculate Partial
Diffrenetiation at each pixel, I am clear with the
formulae of Partial Differentiation, but how to
Implement it.
Thank You,
GAGAN ANAND
