IAmSuyogJadhav / ssh-to-gcp-as-root.md
Created September 6, 2019 19:38
SSH to your GCP Instance as the root user.even when outbound SSH port (22) is blocked on your local system.

On Local System

  1. Run the following command to generate a key.
$ ssh-keygen

You'll be asked to enter passphrase. You can leave that empty.

IAmSuyogJadhav / FourierShift2D.py
Last active April 15, 2021 22:40
2D shifting in python. Accepts both real and complex inputs. Accepts integer as well as floating-point values for shifting. Allows for subpixel shifting of both real and complex 2D matrices/images in python. Based on: https://github.com/aludnam/MATLAB/blob/master/image_proc/FourierShift2D.m

"""
FourierShift2D(x, delta)
Subpixel shifting in python. Based on the original script (FourierShift2D.m)
by Tim Hutt.
Original Description
--------------------
Shifts x by delta cyclically. Uses the fourier shift theorem.
Real inputs should give real outputs.
