A score-based fusion for face verification is presented from FRAV3D Face Database (2D, 2.5D and 3D face images). In the case of 2.5D and 3D data, an automatic correction of pose has been carried out by detecting the nose tip and the eyes. For each kind of image a different feature extraction has been applied (Principal Component Analysis and Support Vector Machine for 2D and 2.5D, and Iterative...

As a recently proposed technique, sparse representation based classification (SRC) with l1-normminimization has been widely used for frontal face recognition (FFR). SRC first codes a testing sample as a sparse linear combination of all the training samples, and then classifies the testing sample by evaluating which class leads to the minimum representation error. But, it is really not the l1-no...

there have been sparse reports in literature of avulsion and degloving injuries of individual areas of face like the nose, eyelids, ear and even mandible. hemi-facial degloving is extremely rare. we present a case of post-assault degloving of the nose, part of forehead with anterior wall of frontal sinus, entire upper and lower eyelids and the cheek. proper planning and staging of the surgical ...

abstract background: pregnancy can be in conflict with sexual function which can be affected by physical and psychological changes during pregnancy. therefore, comparison of the effect of face‑to‑face education with group education on sexual function during pregnancy in couples was the purpose of this research. materials and methods: in this quasi‑experimental pre‑test post‑test study, 64 pregn...

1] demonstrates that simple schematic faces evoke neural responses comparable to those evoked by photographic face stimuli. The authors argue that this shows that schematic visual stimuli may still validly represent face processing, although it has been argued that such non-photographic faces lack many of the visual properties of the human face. In this commentary I would like to elaborate on t...

cephalometry is an important branch of anthropology in which the dimensions of head and face can be determined. these dimensions are used to show indexes for studying brain growth and formation of all types of head and face. indexes are vary from 65 to 95 for head and 65 to105 for face, which are used to determine 4 international anatomic types of head and 5 international anatomic types of face...

Microproblematica are microfossils whose suprageneric taxonomic status is unknown. Many microproblematica display an encrusting way of life and can therefore be included in the group of “micro-encrusters” that during the Upper Jurassic were conspicuous components of microbial carbonate crusts (e.g. LEINFELDER et al., 1993; SCHMID, 1996; DUPRAZ & STRASSER, 1999, 2002). These forms are widespread...

This paper presents an efficient hybrid system to detect frontal faces in colored images regardless of scale, location, illumination, race, number of faces, and complex background. The general architecture of the proposed system encompasses three methods: skin color segmentation, rule-based geometric knowledge, and neural network-based classifier. In the proposed system, multi-skin color cluste...

We propose a theory of firm that is consistent with empirically observed phenomenon of firms simultaneously engaging in both formal and informal activities. Firms face endogenous probability of auditing that depends on the scale of underreporting of both sales and wages. We characterize the conditions for a firm facing corporate, value added and payroll taxes to hide a part of its activities. U...

Using data drawn from the March Current Population Survey, we find that state and federal minimum wage increases between 2003 and 2007 had no effect on state poverty rates. When we then simulate the effects of a proposed federal minimum wage increase from $7.25 to $9.50 per hour, we find that such an increase will be even more poorly targeted to the working poor than was the last federal increa...
