This booklet constitutes the refereed complaints of the 3rd overseas convention on Biometrics, ICB 2009, held in Alghero, Italy, June 2-5, 2009.

The 36 revised complete papers and ninety three revised poster papers offered have been rigorously reviewed and chosen from 250 submissions. Biometric standards coated by way of the papers are assigned to stand, speech, fingerprint and palmprint, multibiometrics and protection, gait, iris, and different biometrics. moreover there are four papers on demanding situations and competitions that at present are below approach, hence proposing an outline at the evaluate of biometrics.

Example text

We show this initial face in Figure 1. The initial distribution of points was made approximately uniform utilizing a uniform point sampling function in Raindrop Geomagic [12]. Images of fifty images Xj in T were aligned with F1 using ICP. Calculation of 3D Signature: Each of the aligned faces was sampled by searching along the normal vector on F1 at each point pi in S, retrieving the closest intersecting point on Xj. This yields an ordered set of 3D points on the aligned version of Xi, and a set of fifty correspondents {pl, … p50} for each pi.

2 Non-ICP-Based 3D Face Biometrics The methods discussed in this section may utilize ICP in the overall process as we do; however, the key is that they do not use ICP as part of each match-score computation. So regardless of gallery size, ICP is utilized as part of probe preprocessing and is not utilized for each match-score computation. Colbry et al. [9] recognized the issue of a need for a faster ICP technique that does not utilize ICP for each match score computation and presented an approach for faster matching.

Rpi = Eci (a) (2) (b) Fig. 1. (a) The binary masks (top row) which are used for scan pair (same subject) registration (second and third rows) according to the semi-rigid regions of the face using ICP. (b) The shapes of expressions residues (top row) are preserved during the projection on the PCA subspace (second row) whereas significant parts of 3D faces are lost during the same projection (third column). 2 Stage 2: Iterative Estimation of the Residue and Neutral Face In this stage of the decomposition, the part of the 3D face which is preserved during the projection is further decomposed to expression and non-expression parts.
