成人为学前儿童选择动画片的问题与改进策略

成人为学前儿童选择动画片能减少或避免学前儿童受到不良因素的影响。对幼儿教师和家长的调查发现,成人为学前儿童选择动画片的过程中出现了选择主动性不够,尚存在绝对选择权,缺乏专业的、权威的、可操作的选择标准,选择动画片的类型受限等问题。在此基础上,提出履行选择职责,关注学前儿童需求,提高动画片质量,实施国产动画片分级制度,构建动画片资源库,为家长提供相关支持等改进策略。

A matting method based on color distance and differential distance

A new matting algorithm based on color distance and differential distance is proposed to deal with the problem that many matting methods perform poorly with complex natural images.The proposed method combines local sampling with global sampling to select foreground and background pairs for unknown pixels and then a new cost function is constructed based on color distance and differential distance to further optimize the selected sample pairs.Finally,a quadratic objective function is used based on matte Laplacian coming from KNN matting which is added with texture feature.Through experiments on various test images,it is confirmed that the results obtained by the proposed method are more accurate than those obtained by traditional methods.The four-error-metrics comparison on benchmark dataset among several algorithms also proves the effectiveness of the proposed method.
