Creating Visual Objects by Direct Manipulation
Low-cost implementations of graphical user interfaces (GUIs) have relied on the widget library framework. Although conventional widgets are suitable for developing typical GUIs with predetermined interaction styles, application-speci c customization of interactions is rather di cult, especially for a nonprogrammer. Instead, we propose a new framework whereby the GUI designers can arbitrarily co...
متن کاملDirect demodulation of closed-fringe interferograms based on active contours.
We demonstrate a method to directly demodulate closed-fringe interferograms using a kind of active contour called a snake. This method can be used to demodulate a single closed-fringe interferogram when its background illumination and/or contrast terms have a spatial frequency similar to the spatial frequency of the equivalent normalized interferogram. Among other cases, this problematic usuall...
متن کاملMatching of Polygon Objects by Optimizing Geometric Criteria
Despite the semantic criteria, geometric criteria have different performances on polygon feature matching in different vector datasets. By using these criteria for measuring the similarity of two polygons in all matchings, the same results would not have been obtained. To achieve the best matching results, the determination of optimal geometric criteria for each dataset is considered necessary....
متن کاملReconstruction of 3D Objects by Integration of Multiple Range Data
A new approach to integrate range data from multiple viewpoints is described. Complicated objects, for example owers, are observed by a range nder from multiple viewpoints whose relative position is unknown. After simple segmentation, correspondences of regions between two consecutive data are examined. This matching process relies on regions which are not supposed to be in uenced by occlusion....
