This paper describes implementation issues encountered in a project to add force feedback to the X Window System desktop in an attempt to add true “feel” to the window system’s “look and feel”. Haptic additions to the interface include adding ridges around icons and menu items to aid interaction, alignment guides for moving windows, and a number of other enhancements to window manipulation. The...

With the development of high-resolution Synthetic Aperture Radar (SAR) systems, researchers are increasingly paying attention to the application of SAR offset tracking methods in ground deformation estimation. The traditional normalized cross correlation (NCC) tracking method is based on regular matching windows. For areas with different moving characteristics, especially the landslide boundary...

This paper presents fast moving window algorithms for calculating local statistics in a diamond, hexagon, and general polygonal shaped windows of an image which is important for real-time applications. The algorithms for a diamond shaped window requires only seven or eight additions and subtractions per pixel. A fast sparse algorithm only needs four additions and subtractions for a sparse diamo...

A method is proposed for e ciently computing moving average lters in regular octagonal windows, as approximations to circular windows. The algorithm requires thirteen operations per pixel irrespective of window size and is faster than existing Fourier-based and recursive methods for all but the smallest windows. Further, new variance-weighted nonlinear lters are introduced, based on moving aver...

background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...

A moving window decision-making algorithm is proposed for the cleaning schedule optimization of heat exchanger network system subject to fouling in refinery crude preheat train. This designed by incorporating scheme into a conventional multi-period optimal control problem (OCP) framework and has distinct feature that it can efficiently handle complex where long-time horizon considered. When com...
