插值(Interpolation),有时也称为“重置样本”,是在不生成像素的情况下增加图像像素大小的一种方法,在周围像素色彩的基础上用数学公式计算丢失像素的色彩。简单地说,插值是根据中心像素点的颜色参数模拟出周边像素值的方法,是数码相机特有的放大数码照片的软件手段。一、认识插值的算法“插值”最初是电脑术语,后来引用到数码图像上来。图像 Interpolation, sometimes called “resetting a sample,” is a way to increase the pixel size of an image without generating pixels, using mathematical formulas to calculate the color of the missing pixel based on the surrounding pixel color. Simply put, interpolation is based on the color parameters of the central pixel simulation peripheral pixel values, digital camera is unique to enlarge the digital photo software means. First, recognize the interpolation algorithm “Interpolation” was originally a computer terminology, and later reference to the digital image. image
