Enable Windows Switching in Ubuntu 14.04 LTS within Gnome-Fallback-Session

Posted on by

Strangely,  Ubuntu 14.04 LTS (and previous versions, down to 10.04), loses it’s alt-tab feature for switching between windows. A feature which you definetely want back, as you use it constantly.

Fortunately it’s very easy to get the feature back:
Launch a terminal and install the CompizConfig Settings Manager, by typing:
“sudo apt-get install compizconfig-settings-manager && sudo apt-get install compiz-plugins”

Start the CompizConfig Settings Manager, by typing: “ccsm”.

In the left pane, navigate to “Window Management”. Remove the checkbox (if checked) for the Application Switcher, and check the box for “Static Application Switcher”.

You should now be able to <alt+tab> your way through your windows again.

Finding robust features in deformable objects.

Tricky business coming up.

For now, I’m diving into SIFT and SURF, which aren’t exactly designed to find features in deformable objects, but it’s a place to begin, if you want to learn about finding features.

SIFT (Left) | SURF (Right)

SIFTSURF

Are exactly the same here. This is also to be expected, since SURF is a derivative of SIFT.
