I want to apply tilt shift to RGB image data acquired by azure kinect


I want to apply a tilt shift to an RGB image acquired with azure kinect.
(I want to apply an effect like the one in this image.https://i.pinimg.com/originals/1b/fe/7c/1bfe7c9c76337d3c35a8cfb51c4fef93.jpg)

However, the depth TOP cannot input the depth image of azure kinect TOP, only the Render TOP can be input.
Even if I generate a point cloud from the azure kinect TOP and use its Render TOP, the lens settings will be shifted when superimposing the RGB image.

Please let me know if there is a better way to apply tilt shift to RGB images taken with azure kinect.
