We know something about the fidelity with which motion can be detected in local regions of the visual field but nothing about how these local motion signals are combined across space to define contours. To investigate such linking rules, we measured the detectability of motion-defined contours using an adaptation of the paradigm of Field, Hayes, and Hess (Vision Research, 33 (1993) 173) in whic...
To determine delivered dose to the spinal cord, a technique has been developed to propagate manual contours from kilovoltage computed-tomography (kVCT) scans for treatment planning to megavoltage computed-tomography (MVCT) guidance scans. The technique uses the Elastix software to perform intensity-based deformable image registration of each kVCT scan to the associated MVCT scans. The registrat...

most of the contour detection methods suffers from some drawbacks such as noise, occlusion of objects, shifting, scaling and rotation of objects in image which they suppress the recognition accuracy. to solve the problem, this paper utilizes zernike moment (zm) and pseudo zernike moment (pzm) to extract object contour features in all situations such as rotation, scaling and shifting of object i...
