Anatomical landmarks are defined as biologically meaningful loci that can be unambiguously defined and repeatedly located with a high degree of accuracy and precision. The neurocranial surface is characteristically void of such loci. We define a new class of landmarks, termed fuzzy landmarks, that will allow us to represent the form of the neurocranium. A fuzzy landmark represents the position ...
In this paper, we introduce a new method to automatically detect useful landmarks for visual SLAM. Landmarks are detected by a biologically motivated attention system. Various experimental results on real-world data show that the landmarks are useful with respect to be tracked in consecutive frames and to enable closing loops.
This paper presents a novel approach for acetabular alignment during the implant of a prosthetic hip joint in a natural pelvis. The alignment instrument uses selective anatomic bony landmarks on the pelvis, which are accessible in surgery, to guide the placement of the acetabular component in the appropriate orientation. A closed form solution, involving both a forward and reverse analysis, is ...
BACKGROUND The use of different coordinate system definitions for the patella leads to difficulties in comparing kinematic results between studies. The purpose of this work was to establish the effect of using a range of coordinate system definitions to quantify patellar kinematics. Additionally, intra- and inter-investigator repeatabilities of the digitization of anatomic landmarks on the pate...
Knowledge on the fish species is important in habitat protection management. This study was conducted to compare the morphological characteristics of two populations of Rhinogobius similis from Hariroud basin based on landmark morphometric truss network system. A total of 60 individuals from Polkhatoun (30 specimens) and Tafrihgah dam (30 specimens) stations were caught by electrofishing 220 vo...
