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 ... -
Energy efficient cosine similarity measures according to a convex cost function
Akbaş, Cem Emre; Günay, Osman; Taşdemir, Kasım; Çetin, A. Enis (SPRINGER LONDON LTD236 GRAYS INN RD, 6TH FLOOR, LONDON WC1X 8HL, ENGLAND, 2017)We propose a new family of vector similarity measures. Each measure is associated with a convex cost function. Given two vectors, we determine the surface normals of the convex function at the vectors. The angle between the ... -
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 ... -
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 ... -
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 ...
