In this paper, we propose a new ridge-type estimator called the new mixed ridge estimator (NMRE) by unifying the sample and prior information in linear measurement error model with additional stochastic linear restrictions. The new estimator is a generalization of the mixed estimator (ME) and ridge estimator (RE). The performances of this new estimator and mixed ridge estimator (MRE) against th...

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...

Automatic Fingerprint Identification Systems (AFIS) are usually based on minutiae matching. Minutiae are the terminations and bifurcations of the ridge lines in a fingerprint image. Detection of ridge lines from a noisy gray-scale fingerprint image is a challenging task. In this work, a novel combinatorial approach is proposed for classifying each pixel into one of the three classes (crest, val...

Gender identification from fingerprints is an imperative footstep in forensic science in order to deliver fact-finding hints for finding anonymous persons. Fingerprint verification is unquestionably the most honest and satisfactory substantiation till date in the court of law. Due to the massive potential of fingerprints as an effective technique of identification an attempt has been made in th...

Haustral folds are a major source of false positives (FPs) in the Computer Aided Detection (CAD) of colorectal lesions. In this paper, a novel bottom-up data-driven approach is presented to globally analyze haustral folds. Unlike the earlier haustral fold detection methods that rely solely on local differential geometric computations, which can be unreliable, particularly for thicker folds, our...

This paper briefly introduces two classic algorithms for fingerprint image processing, which include the soft threshold denoise algorithm of wavelet domain based on wavelet domain and the fingerprint image enhancement algorithm based on Gabor function. Contourlet transform has good texture sensitivity and can be used for the segmentation enforcement of the fingerprint image. The method proposed...

discussion this segmental ridge-split procedure with gradual bone expansion provides a quicker method wherein an atrophic ridge can be predictably expanded and eliminating the need for a second surgical site. this technique also shows that immediate implantation in split ridge of mandible can be performed. introduction narrow alveolar ridges especially in posterior mandibular remains a serious ...

This paper describes a method for the detection of tracking of elongated structures that is robust under changes of scale and orientation. This method is based on extending the concept of scale invariant natural interest points to include elongated ridge structures. An operator is proposed that directly detects ridge points and provides an estimation of their elongation and orientation. A track...
