Graphics And Image Local Deformation Based On Moving Least Squares Method, Xiaorong Du, Shuwen Ping, Zhang Yong
Journal of System Simulation
Abstract: Combined with Moving Least Squares method, a deformation function based on control points and area was defined. A localization processing method for image deformation was proposed which extended to vector graph deformation. After adding control points to control deformation and setting the target deformation zone as control area, control points were controlled to deform image and vector graph, which could produce affine transformation, similarity transformation and rigid transformation results. Experiments show that, this method can inhibit boundary aliasing as well as ensuring graphics and image local deformation result smoothness. By applying it to vector graph deformation, multiple complex deformation …

Journal of System Simulation
Abstract: Aiming at automatic character information acquisition for maize ear analysis, a pipelining mechanism was designed including two main modules: weight measurement and images collection. The system supported automatic collection of weight data and images in batches. And then, the system was analyzed in mechanical properties by kinematic parameters. A three-dimensional simulation system was developed by use of computer graphics technologies to evaluate the performance of the presented pipelining mechanism. The feasibility of the design for maize ear analysis was discussed, which can support high precise and efficient maize ear analysis as a practical tool and technical references.
