MultiColoc will compute all the colocalisation between all possible pairs of objects, each type of object will be defined in a separate labelled image. The colocalisation is defined here as the volume of the intersection between two objects.
In this example left image(A) has 6 objects and right image(B) has 4 objects. The ColocAll results table display all the possible colocalisation between objects in A and objects in B. Objects are labelled with their pixel value in the image. Object A1 correspond to object having value 1 in image A. Same for objects in B, they are labelled with their pixel values.
The ColocOnly results table display for each object A the list of objects in B colocalised with the object in A, O is the object value in B, V is the colocalised volume between object A and object B, and P is the percentage of object in A colocalised with object in B.
