Automatic Segmentation of Small Pulmonary Nodules in Computed Tomography Data Using a Radial Basis Function Neural Network with Application to Volume Estimation (Timothy R. Tuinstra) Faculty Dissertations (2008)

Lung cancer continues to be the leading cause of cancer death in the United States. The automatic detection and characterization of this deadly form of cancer is an area of ongoing research. This dissertation focuses ...

High Resolution Image Reconstruction from Digital Video by Exploitation of Non-global Motion (Timothy R Tuinstra) Engineering and Computer Science Faculty Publications (1998)

Journal Articles (4)

Segmentation of Pulmonary Nodules in Computed Tomography Using a Regression Neural Network Approach and Its Application to the Lung Image Database Consortium and Image Database Resource Initiative Dataset (Temesguen Messay, Russell C. Hardie and Timothy R. Tuinstra) Medical Image Analysis (2015)

We present new pulmonary nodule segmentation algorithms for computed tomography (CT). These include a fully-automated (FA) system, a semi-automated (SA) system, and a hybrid system. Like most traditional systems, the new FA system requires only ...

High Resolution Image Reconstruction from Digital Video by Exploitation of Non-global Motion (Timothy R Tuinstra and Russell C. Hardie) Optical Engineering (1999)

Many imaging systems utilize detector arrays that do not sample the scene according to the Nyquist criterion. As a result, the higher spatial frequencies admitted by the optics are aliased. This creates undesirable artifacts in ...

High-Resolution Image Reconstruction from Digital Video by Exploitation of Nonglobal Motion (Timothy R. Tuinstra and Russell C. Hardie) Optical Engineering (1999)

Many imaging systems utilize detector arrays that do not sample the scene according to the Nyquist criterion. As a result, the higher spatial frequencies admitted by the optics are aliased. This creates undesirable artifacts in ...

Range and Velocity Disambiguation in Medium PRF Radar with the DBSCAN Clustering Algorithm (Timothy R. Tuinstra) 2016 IEEE National Aerospace and Electronics Conference (NAECON) and Ohio Innovation Summit (OIS) (2016)

Disambiguation in range and velocity is a key aspect of target detection in medium PRF radar systems. In this work, the DBSCAN clustering algorithm is applied to the disambiguation problem. The algorithm has been tested ...

Applying the Reformational Doctrine of Christian Vocation to our Understanding of Engineering as a Sacred Calling (Timothy R Tuinstra) Proceedings of the 6th Christian Engineering Education Conference (2006)

Students at Christ-centered universities often find themselves wrestling with whether or not God can use them as effectively in the field of engineering as He can in a field such as pastoral ministry or foreign ...

High Resolution Reconstruction of Digital Video with Non-global Rigid Body Motion (Timothy R Tuinstra and Russell C. Hardie) SPIE Proceedings (1998)

Many imaging systems utilize detector arrays that are not sufficiently dense to sample the scene according to the Nyquist criterion. As a result of this undersampling, some of the higher spatial frequencies admitted by the ...
