一种新的视频缩放算法(英文)

A Novel Algorithm for Video Zooming

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。

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.
