Keynote: Role of Image Processing, Navigation and Robots in Image-guided Intervention

چکیده
Locality-sensitive hashing has been applied in several problems in bioinformatics to quickly search large sequences by examining the n-grams of the sequences. We observe in these application a bias in the random generation of hashes and define an effective equivalence for hashes that generate nearly identical results. Methods that address these two points demonstrate an improvement to the rate at which unique hashes are generated, especially when many hashes are generated. These methods can be easily integrated with existing applications of locality-sensitive hashing, resulting in improved performance by reducing the time algorithms spend revisiting duplicate hashes and eliminating search biases.

Ultra-Fast Image Reconstruction of Tomosynthesis Mammography Using GPU
Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...
متن کاملQuadrotor UAV Guidence For Ground Moving Target Tracking
The studies in aerial vehicles modeling and control have been increased rapidly recently. In this paper , a coordination of two types of heterogeneous robots , namely unmanned aerial vehicle (UAV) and unmanned ground vehicle (UGV) is considered. In this paper the UAV plays the role of a virtual leader for the UGVs. The system consists of a vision- based target detection algorithm that uses the ...
متن کاملMotion detection by a moving observer using Kalman filter and neural network in soccer robot
In many autonomous mobile applications, robots must be capable of analyzing motion of moving objects in their environment. Duringmovement of robot the quality of images is affected by quakes of camera which cause high errors in image processing outputs. In thispaper, we propose a novel method to effectively overcome this problem using Neural Networks and Kalman Filtering theory. Thistechnique u...
