Automated quantification of immunomagnetic beads and leukemia cells from optical microscope images
Uslu, Fatma; Icoz, Kutay); Tasdemir, Kasim; Yilmaz, Bulent (ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2019)Quantification of tumor cells is crucial for early detection and monitoring the progress of cancer. Several methods have been developed for detecting tumor cells. However, automated quantification of cells in the presence ... -
BLSTM based night-time wildfire detection from video
Agirman, Ahmet K; Tasdemir, Kasim (Public Library of Science, 2022)Distinguishing fire from non-fire objects in night videos is problematic if only spatial features are to be used. Those features are highly disrupted under low-lit environments because of several factors, such as the ... -
Deep learning based semantic segmentation and quantification for MRD biochip images
Çelebi, Fatma; Tasdemir, Kasim; Icoz, Kutay (ELSEVIER SCI LTD, 2022)Microfluidic platforms offer prominent advantages for the early detection of cancer and monitoring the patient response to therapy. Numerous microfluidic platforms have been developed for capturing and quantifying the tumor ... -
EXTRACTING PRNU NOISE FROM H.264 CODED VIDEOS
Altinisik, Enes; Tasdemir, Kasim; Sencar, Husrev Taha (IEEE COMPUTER SOC, 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA, 2018)Every device equipped with a digital camera has a unique identity. This phenomenon is essentially due to a systematic noise component of an imaging sensor, known as photo-response non-uniformity (PRNU) noise. An imaging ... -
Image-analysis based readout method for biochip: Automated quantification of immunomagnetic beads, micropads and patient leukemia cell
Uslu, Fatma; Icoz, Kutay; Tasdemir, Kasim; Dogan, Refika S.; Yilmaz, Bulent (PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2020)For diagnosing and monitoring the progress of cancer, detection and quantification of tumor cells is utmost important. Beside standard bench top instruments, several biochip-based methods have been developed for this ... -
Image-Processing Based Signal Readout Method for MRD Biochip
Uslu, Fatma; Icoz, Kutay; Tasdemir, Kasim (IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2019)The response of the cancer patients to chemotherapy treatment varies from person to person. For some patients cancer cells are resistant to treatment and these cells can relapse again which is known as minimal residual ... -
Improved senescent cell segmentation on bright-field microscopy images exploiting representation level contrastive learning
Çelebi, Fatma; Boyvat, Dudu; Ayaz-Guner, Serife; Tasdemir, Kasim; Icoz, Kutay (WILEY Online Library, 2024)Mesenchymal stem cells (MSCs) are stromal cells which have multi-lineage differentiation and self-renewal potentials. Accurate estimation of total number of senescent cells in MSCs is crucial for clinical applications. ... -
Mitigation of H.264 and H.265 Video Compression for Reliable PRNU Estimation
Altinisik, Enes; Tasdemir, Kasim; Sencar, Husrev Taha (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA, 2020)The photo-response non-uniformity (PRNU) is a distinctive image sensor characteristic, and an imaging device inadvertently introduces its sensor's PRNU into all media it captures. Therefore, the PRNU can be regarded as a ... -
Mixture of Learners for Cancer Stem Cell Detection Using CD13 and H&E Stained Images
Oguz, Oguzhan; Akbas, Cem Emre; Mallah, Maen; Tasdemir, Kasim; Guzelcan, Ece Akhan; Muenzenmayer, Christian; Wittenberg, Thomas; Uner, Aysegul; Cetin, A. Enis; Atalay, Rengul Cetin (SPIE-INT SOC OPTICAL ENGINEERING, 1000 20TH ST, PO BOX 10, BELLINGHAM, WA 98227-0010 USA, 2016)In this article, algorithms for cancer stem cell (CSC) detection in liver cancer tissue images are developed. Conventionally, a pathologist examines of cancer cell morphologies under microscope. Computer aided diagnosis ... -
PRNU Estimation from Encoded Videos Using Block-Based Weighting
Altinisik, Enes; Tasdemir, Kasim; Sencar, Hüsrev Taha (Society for Imaging Science and Technology, 2021)Estimating the photo-response non-uniformity (PRNU) of an imaging sensor from videos is a challenging task due to complications created by several processing steps in the camera imaging pipeline. Among these steps, video ... -
A review of mammographic region of interest classification
Yengec Tasdemir, Sena B.; Tasdemir, Kasim; Aydin, Zafer (WILEY PERIODICALS, INC, ONE MONTGOMERY ST, SUITE 1200, SAN FRANCISCO, CA 94104 USA, 2020)Early detection of breast cancer is important and highly valuable in clinical practice. X-ray mammography is broadly used for prescreening the breast and is also attractive due to its noninvasive nature. However, experts ... -
ROI Detection in Mammogram Images using Wavelet-Based Haralick and HOG Features
Tasdemir, Sena Busra Yengec; Tasdemir, Kasim; Aydin, Zafer (IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2018)Digital mammography is a widespread medical imaging technique that is used for early detection and diagnosis of breast cancer. Detecting the region of interest (ROI) helps to locate the abnormal areas, which may be analyzed ... -
