Fusion of face recognition method Research Paper

Fusion of face recognition method - Research Paper Example Figure 3 details these matches considering Amber1 and Andy2 (dashed arrows points to some of the analogous features that may be distinguished from the eigenface). It was observed (from Figure 1 and 2) that Amber1 have more distinguished features from the eigenface. Thus we can say that the eigenface closely and strongly resembles Amber1. Amber1's reconstructed images (shown in Figure 5 - include the step by step reconstruction of Amber1's face contained in folder "ReconstructedPictures") supports this observation. Before finding the eigenfaces, however, 'we first need to collect a set of face images. These face images become our database of known faces. We will later determine whether or not an unknown face matches any of these known faces. All face images must be the same size (in pixels), and for our purposes, they must be grayscale (shown in Figure 6), with values ranging from 0 to 255' (Krueger, J, et al, "Obtaining the Eigenface Basis"). Eigenfaces are basically basis vectors for real faces. This can be related straightforwardly to one of the most basic concepts in electrical engineering: Fourier analysis. Fourier analysis discloses that "a sum of weighted sinusoids at differing frequencies can recompose a signal perfectly"! In the same manner a "sum of weighted eigenfaces can seamlessly reconstruct a specific person's face". (Krueger, J, et al, "Obtaining the Eigenface Basis") CONCLUSION According to Krueger, J. & et al, "the eigenface technique is a powerful yet simple solution to the face recognition dilemma. In fact, it is really the most intuitive way to classify a face. As we have shown, old techniques focused on particular features of the face. The eigenface technique uses much more information by classifying faces based on general facial patterns. These patterns include, but are not limited to, the specific features of the f

Federalism Term Paper Example | Topics and Well Written Essays - 750 words

Federalism - Term Paper Example Federalism in the US has evolved in the course of the nation’s history from Dual Federalism between 1789 and 1945 after WWII, to Cooperative Federalism between 1945 and 1969 and finally New Federalism from 1969 to present (Robertson, 2012). However, there were also some changes to federalism between Dual Federalism and Cooperative Federalism, especially those occasioned by the 1861-1868 Civil War followed by the Fourteenth Amendment. Then industrialization and globalization that set in between 1865 and 1945, which culminated in the federal government taking over power from state governments when Franklin Roosevelt’s presidency made efforts to revive the economy after the Great Depression. The nation’s first 150 years were described by Dual Federalism, where the Constitution provided for state and national governments. The national government presided over national defense, fostering commerce and foreign policy. On the other hand, state governments dealt with crim inal law, economic regulation and local issues. Each having a distinct area of jurisdiction, the two governments rarely overlapped. Cooperative Federalism marked the intertwining of state and federal authority, where it became difficult to demarcate the beginning and end of the authority of each type of government because they both administered numerous federal programs simultaneously. However, in order to finance their own programs and initiatives, states heavily relied on the federal government for funds.
