متن کاملAutomatic detection of liver tumor motion by fluoroscopy images
Background: A method to track liver tumor motion signals from fluoroscopic images without any implanted gold fiducial markers was proposed in this study to overcome the adverse effects on precise tumor irradiation caused by respiratory movement. Materials and Methods: The method was based on the following idea: (i) Before treatment, a series of fluoroscopic images corresponding to different bre...
متن کاملActive Pixel image Sensor with Motion Detection
This 256x256 active pixel sensor (APS) is designed for consumer multimedia applications requiring low-cost, high-functionality, compact cameras capable of acquiring highquality images at video frame rates. This sensor allows random access of the image data, permitting a simple implementation of electronic pan and zoom. Use in portable equipment is simplified by standard operatingvoltages andlow...
متن کاملIdeal Observers for Detecting Motion: Correspondence Noise
We derive a Bayesian Ideal Observer (BIO) for detecting motion and solving the correspondence problem. We obtain Barlow and Tripathy’s classic model as an approximation. Our psychophysical experiments show that the trends of human performance are similar to the Bayesian Ideal, but overall human performance is far worse. We investigate ways to degrade the Bayesian Ideal but show that even extrem...
متن کاملMicrolensing Parallax for Observers in Heliocentric Motion
Motivated by the ongoing Spitzer observational campaign, and the forecoming K2 one, we revisit, working in an heliocentric reference frame, the geometrical foundation for the analysis of the microlensing parallax, as measured with the simultaneous observation of the same microlensing event from two observers with relative distance of order AU. For the case of observers at rest we discuss the we...
