Data Access

Data Access

In order to establish how the data is going to be accessed, the module DataAccess provides an unified interface to access to the data for the underlaying algorithms. Every DataAccessor must implement this two methods:

  1. get_element(d::T, X, i::Integer). This function must return the i-th pattern of X.
  2. number_of_patterns(d::T,X). This function must return the numer of patterns of X

SpectralClustering.get_element! — Method.
get_element!{T<:AbstractArray}(vec::T,  img::Matrix{Gray}, i::Integer)

Return throughvec the intensity image element [x,y, i], where $x,y$ are the spatial position of the pixel and the value i of the pixel $(x,y)$.
