DiffImg is a simple image comparison tool which take two images with the same size as input. Some statitics are computed and the positions where pixel differ are displayed as a color mask.
There are very few image difference tools for Ubuntu Linux. DiffImg is one of them which has a user friendly GUI. It uses OpenCV as backend so it can read and compare 8/16/24/32 bits images without problem but only single channel and RGB image has been take into account, so alpha channel isn’t supported.
Because DiffImg is written with Qt, it runs on Windows and Linux (MacOSX isn’t tested yet) and OS/2. It can read basic formats as BMP, PNG, JPG but also Tiff and OpenExR.
Current Features:
Image difference display : a yellow/red mask can overlay the original/modified images.
Single/Dual panels mode.
Statistic computation: Mean error, RMS error and min/max are computed.
Several metrics can be used for computing image difference.
Histogram of error.
“Slideshow” : DiffImg can compare directory of image, so you can switch to the previous/next comparison if you have two folders with the same image list.
Supported files :DifffImg uses Qt plugins to load images, so by default it can read basic formats as BMP, PNG, JPG and OpenCV supported formats (Tiff, OpenExR).
Basic batch mode

A PPA repository has been created to make it easy to install for Ubuntu and Linux Mint users. So far, it supports Ubuntu 13.04 Raring, 12.10 Quantal, 12.04 Precise and Linux Mint 13 Maya, 14 Nadia, 15 Olivia.

This brief tutorial shows you how to change your laptop touchpad tap actions in Ubuntu, including single tap, two and three finger tap as well as tap on corners..
I’m only using single tap and touchpad scrolling feature on my laptop. As you may know, Ubuntu acts as middle click when tapping on top-right corner of touchpad. It is annoying that I was always ‘corner-tapping’ on my Google Chrome tabs, and they vanished all of a sudden. More over, two finger tap brings up righ-click menu, quick tapping twice on title-bar, browser tabs allows to move items. Due to these useless and annoying tap actions (only for me), I’m determined to tweak my touchpad settings. That’s why I’m writting this tutorial.
The default Mouse & Touchpad utility in Ubuntu Unity is getting better now, but it’s not powerful enough. So far it only has the ability to switch on / off touchpad, Tap to click, Disable while typing, Two finger scroll, Contents sticks to fingers as well as point speed settings.
I found synaptiks, which is a simple utility that covers almost all settings of Synaptics Touchpad, including multi-tapping, tapping on corners. It is available on Ubuntu Software Center by default since Ubuntu 12.04 Precise. Click link below to install it:
When installed, open the tool and go to Touchpad Configuration -> Tapping. There provides options to change tapping on 4 corners, single tap, two finger tap, three finger tap, drag items by tapping, etc.
