Abstract: Inspired from the quantum mechanics, the authors propose a novel and practical video zooming algorithm which has a better image quality than other methods. Compared to the quantum mechanics models , an image is treated as a energy field and modify the traditional cardinal spline function. This method reduces the sample effect across the edges and improves the human pleasure. The proposed method has a low complexity, and keeps the coherence between frames for video sequence. It is especially suit for the embedded equipments such as mobile phones and PDAs.

摘要： 基于量子力学新模型, 提出一种新的实用的图像缩放算法, 使得处理后的视频能有很好的图像质量。不同于量子力学中的一些模型, 新方法将图像看做一个连续的能量场。此方法修改了传统的基数样条函数, 并通过减少跨越图像物体边缘的采样来增加视觉的舒适度。该算法具有复杂度低和一致稳定的特点, 特别适合用于嵌入式设备, 如手机及PDA。
