Estimation of Gestational Age by Amniocentesis
Gynecologic and Obstetric Investigation, 2010We have previously demonstrated that gestational age can be estimated from a diagram in which the percentage of lipid-carrying cells (amniotic fluid cytology) and the creatinine concentration in the amniotic fluid are plotted. Using this diagram for the purpose of dating, a comparison was made with prediction of gestational age by early ultrasound ...

Subjective Time Estimation and Age
Perceptual and Motor Skills, 1991Time seems to accelerate with increasing age. This subjective acceleration or compression may be due to the operation of a linear or a square-root function that relates present age to past age. A subjective magnitude-estimation technique was applied in a questionnaire given to 282 university students to determine which function best fitted the data ...

Molecular pathology and age estimation
Forensic Science International, 2010Over the course of our lifetime a stochastic process leads to gradual alterations of biomolecules on the molecular level, a process that is called ageing. Important changes are observed on the DNA-level as well as on the protein level and are the cause and/or consequence of our 'molecular clock', influenced by genetic as well as environmental ...

Deep probabilities for age estimation
2017 IEEE Visual Communications and Image Processing (VCIP), 2017Human age can provide important demographic information. In this paper, we tackle the estimation of age in face images with probabilities. The design of the proposed method is based on the relative order of age labels in the database. The age estimation problem is transformed into a series of binary classifications achieved by convolution neural ...

Automatic Age Estimation: A Survey
Computación y Sistemas, 2020Since, aging is non-reversible process. Human face and gait change with time which reflects major variations in appearance, the vast majority of people are able to easily recognize human traits like emotional states, where they can tell if the person is happy, sad or angry from the face, likewise, it is easy to determine the gender of the person ...

A Study on Apparent Age Estimation
2015 IEEE International Conference on Computer Vision Workshop (ICCVW), 2015Age estimation from facial images is an important problem in computer vision and pattern recognition. Typically the goal is to predict the chronological age of a person given his or her face picture. It is seldom to study a related problem, that is, how old does a person look like from?the face photo? It is called apparent age estimation.

Age estimation in competitive sports
International Journal of Legal Medicine, 2016To maintain the principle of sporting fairness and to protect the health of athletes, it is essential that age limits for youth sporting competitions are complied with. Forensic scientists have developed validated procedures for age estimation in living individuals. Methods have also been published for age estimation in competitive sports.

Ultrasound Estimation of Gestational Age
Clinical Obstetrics and Gynecology, 1984Many ultrasonologists feel that if they are unable to obtain a BPD measurement at the time of an ultrasound examination that they have somehow failed to do an adequate job. However, from the information outlined in this chapter, it can be seen that the biparietal diameter is only one measurement that can be taken of the fetus in order to estimate ...

Advances in forensic age estimation
Forensic Science, Medicine, and Pathology, 2011The ability to assign accurate age estimates to human remains and living individuals is becoming an increasingly important element of forensic practice. In mass fatality events, where many people lose their lives and are often unable to be visually identified, being able to separate individuals based on their age as determined by skeletal and/or dental
