Moran's Index

Compute Moran's Index for images or adjacency matrices

---

Installation

You can install moransi via pip:

pip install moransi

To install latest development version :

pip install git+https://github.com/GuignardLab/moransi.git

Usage

You can use this code after installing it the following way:

from moransi import morans_i_image

image = ... # opening an image
kernel = ... # A kernel for the weights of the neighbouring pixels

morans_i_image(image, kernel) # Returns the Moran's index

from moransi import morans_i_adjacency_matrix

adjacency_matrix = ... # an adjacency matrix of size N by N.
                       # It is either binary or links weights
                       # adjacency_matrix[i, j] is >0 if there is an edge
                       # between i and j
metric = ... # An array of size N where metric[i] is the value of node `i`

morans_i_adjacency_matrix(image, metric) # Returns the Moran's index
