Algorithm 1. Cardiac deep learning algorithm

// Get MRI image samples and set the range;
Input: A_in; Output: A_out;
// Segment the images;
For each cluster pair (A_{x_in}, A_{y_in})
                    If min(A_{x_in}, A_{y_in}) × |Q_{x_in} − Q_{y_in}|
                    Then merge A_{x_in}, A_{y_in} into A_z;
//Feature extraction;
                    AZ_i = AZ_{x_in} + AZ_{y_in};
                      Q_i = (AZ_{x_in} × Q_{x_in}) + (AZ_{y_in} × Q_{y_in})/(AZ_{x_in} + AZ_{y_in});
//Preprocessing of samples;
                      Where A_in is the x × y matrix;
                      For I = 1:x
                      For j = 1:y
                      If (A_in(x,y) < 0
                      A_in_s = 1;
                      Else
                      A_in_s = 0;
