Human Being Detection By Robotic Eye
One of the widely used approaches in image recognition is Principle Component Analysis(PCA) because of the
good balance between the speed and simplicity of the algorithm and the results by using it. In the last years many variants of
PCA were developed: two dimensional PCA, two directional two dimensional PCA, extended two dimensional PCA and
extended two dimensional two directional PCA, the last one developed by the first two authors of the present paper. In this
paper we go further with this study by considering a mixed approach between E2DPCA and diagonal PCA. The mixed
approach not only takes approximately the same amount of time for training and testing as the classical approach, but also
gives better recognition accuracy for some of the PCA algorithm variants.
