This statistical primer presents the landmark analysis method, exploring its appropriate use and interpretation while recognizing its limitations. This observational method is used for comparing time-to-event outcome between groups determined during study follow-up. The goal of the landmark method is to estimate in an unbiased way the time-to-event probabilities in each group conditional on the...

conclusions in our conditions, the use of an anatomical landmark-guided procedure was the preferred treatment method due to limited resources and a lack of adequate training. background central venous cannulation is a current and important procedure used in the operating room and intensive care unit. some studies have shown that the application of ultrasound-guided cannulation can improve the s...

Mainly motivated by statistical shape analysis, this paper presents a novel landmark-based method for accurate shape correspondence, where the general goal is to align multiple shape instances by identifying a set of corresponded landmark points along those shapes. Different from previous methods, we consider both global shape deformation and local geometric features in defining the shape-corre...

Facial landmark detection is an essential initial step for a number of facial analysis research areas such as expression analysis, 3D face modeling, facial attribute analysis, and person recognition. It is a well researched problem that has seen a surge of interest in the past couple of years. However, most state-of-the-art methods still struggle in the presence of extreme head pose, especially...

geometric morphometric method was used to examine body shape variations among all the seven valid species of the genus alburnus in iran. in total 409 specimens of a. chalcoides, a. filippii, a. atropatenae, a. caeruleus, a. mossulensis, a. hohenackeri and a. zagrosensis were collected from babolrud, baleqlu-chai, miriseh, sarabeleh, gamasiyab, mahabad-chai rivers and the gandoman lagoon, respec...

A foot database comprising 3D foot shapes and footwear fitting reports of more than 300 participants is presented. It was primarily acquired to study footwear fitting, though it can also be used to analyse anatomical features of the foot. In fact, we present a technique for automatic detection of several foot anatomical landmarks, together with some empirical results.
