Algorithm 1 Late fusion (decision fusion) using fuzzy integral.

procedureFuzzy –Integral

Calculate $\lambda$;

for each action class $c_k$ do

for each classifier $x_i$ do

Compute $f_k\left(x_i\right)$

Determine ${\mu }_k\left(\left\{x_i\right\}\right)$

end for

Calculate fuzzy integral for the action class

end for

Find out the action class label

end procedure
