Laboratory mice are frequently used in biomedical studies. Facial expressions of mice provide important data about various issues. For this reason real time tracking of mice provide output to both researcher and software that operate on face image directly. Since body and face of mice is the same color and mice moves fast, tracking of face of mice is a challenging task. In recent years, methods that use artificial neural networks provide effective solutions to problems such as classification, decision making and object recognition thanks to their ability to abstract training dataset. Especially, convolutional neural networks, which are inspired by visual cortex of animals, are very successful in computer vision tasks. In this study, a method based on deep learning which uses convolutional neural networks is proposed for real time tracking of face of mice. Convolutional neural networks are good at extracting hierarchical features from training dataset. High level features contains semantic features and low level features has high spatial resolution. Target information is extracted from combination of low and high leve1673516l features by convolutional layer to achieve robust and accurate tracker. Although proposed method is specialized in tracking face of mouse, it can be adapted any target by changing training dataset.

Mouse face tracking using convolutional neural networks Akkaya, Ibrahim Batuhan; Halıcı, Uğur (2018-03-01) Facial expressions of laboratory mice provide important information for pain assessment to explore the effect of drugs being developed for medical purposes. For automatic pain assessment, a mouse face tracker is needed to extract the face regions in videos recorded in pain experiments. However, since the body and face of mice are the same colour and mice move fast, tracking their face is a challenging task. In recent years, with their ability to learn from data, deep learning provides effective solutions fo...
Assesment of Pain in Mouse Facial Images ERAL, Mustafa; ÇAKIR AKTAŞ, Canan; EREN KOÇAK, EMİNE; DALKARA, TURGAY; Halıcı, Uğur (2016-11-05) Analysing mouse behavior in medical experiments to determine adverse effects of medical drugs requires special expertise and it is a time consuming tedious task. Automatic scaling of facial pain mimics in mice are important for a fast and objective labeling. Although there exists a manual procedure for scaling mouse facial pain expression, a full automatic method does not exist yet. In this paper, a computational method is proposed for assesment of pain through facial exressions of mouses in experiments whe...
Fe3+/SeO42- dual doped nano hydroxyapatite: A novel material for biomedical applications ALSHEMARY, AMMAR ZEIDAN GHAILAN; Pazarçeviren, Ahmet Engin; Tezcaner, Ayşen; Evis, Zafer (2018-01-01) Dual ions substituted hydroxyapatite (HA) received attention from scientists and researchers in the biomedical field owing to their excellent biological properties. This paper presents a novel biomaterial, which holds potential for bone tissue applications. Herein, we have successfully incorporated ferric (Fe3+)/selenate ( SeO42-) ions into the HA structure (Ca10-x-yFey(PO4)(6-x)(SeO4)(x)(OH)(2-x-y)O-y) (Fe-SeHA) through a microwave refluxing process. The Fe-SeHA materials were characterized by X-ray diffra...
A Cell Culture Chip with Transparent, Micropillar-Decorated Bottom for Live Cell Imaging and Screening of Breast Cancer Cells Ermiş Şen, Menekşe; ANTMEN ALTUNSOY, EZGİ; Kuren, Ozgur; Demirci, Utkan; Hasırcı, Vasıf Nejat (2022-01-01) In the recent years, microfabrication technologies have been widely used in cell biology, tissue engineering, and regenerative medicine studies. Today, the implementation of microfabricated devices in cancer research is frequent and advantageous because it enables the study of cancer cells in controlled microenvironments provided by the microchips. Breast cancer is one of the most common cancers in women, and the way breast cancer cells interact with their physical microenvironment is still under investigat...
