Spectrum_Zoom
- 这个函数返回n点2dw波段的傅里叶变换的DFT样本序列。通常情况下,以插值点的方式进行放大。-This function returns N point DFT samples of 2dw band of Fourier transform of a sequence. Typically, fft() returns N samples of Fourier transform ranging from 0 to 2pi. This function takes the N-point DF
Bilinear
- 根据双线性原理,对图像进行插值放大。 设放大比例为s,则k*s+1的点为原来图像上k处的值-The bilinear principle, the interpolation to enlarge the image. Set zoom ratio s, the value k* s+1 points of the original image k at
bacc
- 实现线性插值 可用于图像无损放大 简单易行-Image lossless linear interpolation can be used to zoom simple
Bilinear-interpolation
- 双线性插值,可用于图像的放大,及对像素颜色的插值,能产生光滑的过渡效果-Bilinear interpolation can be used to enlarge the image, and the color of the pixel interpolation, to produce a smooth transition effect
新建文件夹
- 可以使文件中的图像放大两倍,采用双线性插值不失真。(The image magnified two times)
双三次插值
- 三次插值是一种更加复杂的插值方式,它能创造出比双线性插值更平滑的图像边缘。双三次插值方法通常运用在一部分图像处理软件、打印机驱动程序和数码相机中,对原图像或原图像的某些区域进行放大。(Cubic interpolation is a more complex interpolation method that creates a smoother image edge than a bilinear interpolation. The double cubic interpolation m
