Webmethod of projection is different; Eigenface uses PCA while Fisherface uses FLD. PCA works better with dimension reduction and FLD works better for classification of different … WebFisherfaces use features that distinguish one from others instead of using the common feature. Fisherfaces is more efficient when there is a large number of dataset of facial images with various expression. Algorithm: First, we take input images from the database.
