| description | The invention belongs to the technical field of embedded computer image processing, and especially relates to an image scaling method. Methods such as neighbor sampling, bilinear interpolation and bicubic interpolation are generally adopted in image scaling. The invention aims to overcome shortcomings of the existing scaling methods and design a method for image scaling by using a Sinc filter. Theimage scaling method is flexible and diversified in implementation, not only can be implemented by using software, but also can be implemented by using hardware such as a DSP and programmable logic.
本发明属于嵌入式计算机图像处理技术领域，特别是涉及种图像缩放方法。图像缩放般是采用近邻取样法，双线性插值，双三次插值等方法。本发明目的是克服已有的缩放方法的不足，设计种使用Sinc滤波器进行图像缩放的方法。本发明的实现方法灵活多样，既可以使用软件实现也可以使用硬件比如DSP和可编程逻辑实现。 |
