Augmentation of deficient and atrophic alveolar ridges is an important aspect of dental implant therapy with the goal of providing a functional restoration in harmony with adjacent natural dentition. Bone splitting technique is considered a distinguished augmentation method for treatment of deficient alveolar ridges. According to this procedure, the compromised alveolar ridge is opened from the...

Increasingly, reliable absolute frequency and orientation maps are needed, e.g. for image enhancement. Less studied is however the mutual dependence of both maps, and how to estimate them when none is known initially. We introduce a logarithmic scale space generated by the trace of Structure Tensor to study the relationship. The scale space is non-linear and absolute frequency estimation is red...

Sea ice pressure ridges have been recognized as important locations for both physical and biological processes. Thus, understanding the associated light-field is crucial, but their complex structure internal geometry render them hard to study by field methods. To calculate in- under-ridge light field, we combined output from an mechanical model with a Monte-Carlo ray tracing simulation. This re...

Fingerprint verification is an important bio-metric technique for personal identification. Most of the automatic verification systems are based on matching of fingerprint minutiae. Extraction of minutiae is an essential process which requires estimation of orientation of the lines in an image. Most of the existing methods involve intense mathematical computations and hence are performed through...

Software cost estimation is one of the prerequisite managerial activities carried out at the software development initiation stages and also repeated throughout the whole software life-cycle so that amendments to the total cost are made. In software cost estimation typically, a selection of project attributes is employed to produce effort estimations of the expected human resources to deliver a...

We introduce the concept of coverage risk as an error measure for density ridge estimation. The coverage risk generalizes the mean integrated square error to set estimation. We propose two risk estimators for the coverage risk and we show that we can select tuning parameters by minimizing the estimated risk. We study the rate of convergence for coverage risk and prove consistency of the risk es...

We propose to fit a Lancaster-type additive model of interaction terms for cell probabilities of contingency tables to evaluate the conditional probability of population uniqueness of sample unique records in microdata sets. Moment estimation of the Lancaster-type additive model is straightforward and the proposed estimation procedure is intuitively appealing from the viewpoint of disclosure ri...

Mixture models have been popular to solve computer vision problems such as optical flow, object recognition and human pose estimation. In particular, mixtures of classifiers are state-of-the-art approaches to estimate human pose from images. These discriminative approaches learn a functional mapping, or conditional distributions, between image features and 3D poses. However, existing algorithms...
