I suppose I can use the a (apply,lamda) combination but I was wondering if there was another interpolation function that would allow me to do this. For now after trying many different things and getting a bit frustrated I settled on this: y_new= np.array([spln_inter_curve2(x[x],y[...
and There are many types of interpolation such as piece-wise constant, polynomial, linear, basis spline, and cubic spline. In interpolation, the data offer the shape of the approximate function, with piece-wise or higher-order polynomial equations to accurately counterpart the data ...
I would like to interpolate this video fromframesframes to any number of frames, very fast, hopefully with a cubic spline, but any other continuous interpolation will work OK too. The naive solution I have implemented splits the array into 2 arrays of dimensions(frames, points)for theXarray ...

两个图像之间的插值是指通过对两个图像之间的像素进行插值计算,生成一个新的图像。插值可以用于图像处理、计算机视觉和计算机图形学等领域。 插值方法有很多种,常见的包括最近邻插值、双线性插值、双三次插值等。不同的插值方法在保留图像细节和平滑图像之间有不同的权衡。 最近邻插值是一种简单的插值方法,它将目标像...
