It was designed for repair and preview of files downloaded from bittorrent, gnutella, emule, ftp, web or any such source and it can repair AVI and DivX files (for now).
Check out this video tutorial on how to fix broken AVI files with DivFix++ on Ubuntu Linux.ĭivFix++ is an open source AVI video repair and preview software which works on Windows, Linux and Mac OSX. This computer operating system could be a bit tricky for beginners, but fret not, help is here. Nobody wants to watch a video and find out it's corrupted and not working anymore. You can specify a threshold level (essentially a tolerance factor between 0 and 1) if an exact match is not required the threshold can be increased.Broken AVI video files are your worst nightmare. There is a perl program called idiff which is used when testing examples. Pixels_greater_than_one = sum(sum(greater_than_one)) Greater_than_one = (baseline - test) > 1 % produces a matrix of 1s and 0s Test=imread('SigmoideImageFilterCmgui.png')
Here is some Octave code I wrote to determine the number of pixels which differed by more than 1īaseline=imread('SigmoidImageFilter.png') Octave can be used to read images into arrays, which means you can easily manipulate and view the arrays to determine information about the difference between the images. If there is no difference between the images the layer should now appear completely black.
See for more info on the use of compare.Īnother method to visually compare two images to see if they look the same is as follows: If you open up difference.png (using display or gimp) a greyed out version of the image is shown with the areas of difference highlighted in red. You can specify an ouput image which will show the areas which are different and you can also specify various metrics to get a single value which is a measurement of the difference between the filesĬompare -metric AE SigmoidImageFilter.png SigmoidImageFilterCmgui.png difference.png
