about inverse_warp.py

I would like to inquire about the differences between these two functions：
①you：def inverse_warp2(img, depth, ref_depth, pose, intrinsics, padding_mode='zeros')
②cv2.warpPerspective(src，M, dsize[,dst[，flags[， borderMode[ , borderValue]]]]) →dst

[JiawangBian]

at least, the cv2 functions are not differentiable :)

In fact, what I want to achieve is to find the newly added part of frame i+1 relative to frame i of the image
