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.

Key words: video zooming, interpolation, adaptive, quantum mechanics

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。
