Value-added Evaluation System for Vocational School Students Construction and Practice Research

Student evaluation in the new era should be rooted in the educational macro background of"cultivating people by virtue"and comply with the overall policy orientation of educational evaluation reform.This research focuses on the construction and implementation of value-added evaluation system.Combined with the characteristics of vocational school students,this paper constructs a four-level index system and refines the student evaluation standards.The evaluation subjects are students,head teachers,teachers,parents and enterprise managers.Through the development of the related APP,it is convenient for each evaluation subject to input information,and finally use K-line chart to visually present the change process of the appreciation in students'literacy.A value-added evaluation system with strong timeliness,objectivity,motivation and operability is constructed.

改进形状上下文的湍流杂波形状目标匹配识别

针对近地面远距离成像场景下轮廓目标受湍流杂波影响而使匹配误差较大的问题,提出一种基于方向形状上下文和边连续性约束的形状点集匹配识别方法。首先将方向特征嵌入传统的形状上下文来构造一个具有尺度和旋转不变性的特征算子。然后,受模板和目标形状之间的边连续性先验启发,在目标匹配能量代价函数中加入轮廓形状边连续性约束条件以提高形状匹配精度。合成湍流杂波场景和真实远距离成像场景中的形状匹配实验结果表明,和传统方法相比,所提方法能够将杂波场景下的目标匹配误差平均降低约6%,同时还降低了计算复杂度。
