Good day ABHIDNYA PATHARKAR,

the OrientationJ web-page gives a brief introduction but also cites a

number of publications that may help.

Distribution of orientations

The orientation is evaluated for every pixel of the image based on the

structure tensor. A histogram of orientations is built taken into

account the pixel that have a coherency larger than min-coherency and an

energy larger than min-energy. The histogram is a weighted histogram,

the weight is the coherency itself. The min-coherency is expressed is %

since the coherency factor is a index between 0 and 1. The min-energy is

expressed in % of the maximum energy of the image.

"

Please be aware that analyses by OrientationJ are based on local

measurements (structure tensor for each pixel) and as stated above, the

distribution is a weighted histogram of the results of very many of such

local measurements.

In fact there are other methods that measure regionally or globally such

as those described here in great detail:
