Detection of Tubes in Radiographs Using Canny Edge Detection and Progressive Hough Transforms
… automatically detecting tubes that first uses a Canny edge detector for the initial identification of edges, followed by a windowed variant of the Hough transform, a common line detection algorithm, which is used to identify potential tube pixels. Our method employs repeated applications of a …

Automated stenosis quantification in coronary arteriograms
… The scanning approach is accomplished by a canny edge detector. The edge tracking approach is in favor due to its low variability and fast analysis time. Given a start point and search direction, a tracking process automatically detects the arteries edge. From the edge points, a quantitative …

Thieves Apostates and Bloody Viragos: Female Irish Catholic Rebels in the Irish Rebellion of 1641.
… earlier efforts of historians such as Nicholas Canny and Mary O'Dowd. In the course of this thesis, I intended to argue that the actions of Irish Catholic women in the rebellion were largely determined by their social status, geographic location, and prior relationships between female rebels and …

The king at <i>Kaamelott</i>
… this Frankenstein, brought to life through canny theatrical <em>bricolage</em>, provokes the following concrete question: how have the dimensions of the exemplary human life of the King been updated by this installment of an eight centuries (and more) old tradition? Using the frame-work of …

Heterogeneous CPU-FPGA system framework and scheduler
… distribution of image processing tasks using the Canny edge detection algorithm as a representative test case to assess system performance under various workload conditions. Through a comprehensive series of experiments executed within the OpenCL framework, we assess the effectiveness of our task …

Investigation into the use of the Microsoft Kinect and the Hough transform for mobile robotics
… Three edge detectors are used - the LoG, Canny and Sobel edge detectors. These were compared, and the Sobel detector was found to be the best. The _nal process was then used in multiple ways - _rst to determine its speed. Its accuracy was then investigated. It was found that the planes …

GPU Accelerated Refined Tensor Voting
… data. Edge detection algorithms such as the Canny edge detector or the Sobel operator attempt to solve this issue by detecting and isolating image edges. However, they often fail in the presence of noise or extracting higher-level structures. Noise removal techniques such as Gaussian blur …

Accumulator-based three dimensional building boundary reconstruction framework for satellite images
… ABED was compared against Parameter Free Canny Edge Detection (CannyPF) [1] and Parameter Free Edge Drawing (EDPF) [2] for each site. ABED recovered more edge pixels with improved recall for all ten sites. Furthermore, the Root Mean Square Error (RMSE) for edge position errors was less …
