I have a bunch of similar images that are very close in content but maybe just slightly different enough to not be easily perceptible to the human eye. The main problem is that some of the images have differing aspect ratios but I am correcting that manually and resizing the images where needed. My question is is there a similar or equivalent function to the image comparison feature in the Beyond Compare tool. I know IM has compare and convert but BC2 can present the visual equivalent of a diff in a center panel with the two images surrounding it. This seems to be some of sort of XOR'ing operation similar to compare in IM but with a tolerance slider as well as some other options. I've tried the basic compare functions - and while very useful - are not exactly what I intended to produce. Is there a way to approximate this behavior in IM? I noticed that convert has a compose XOR option and I thought this may be a way to highlight the major differences between the two. (I am not so much concerned with palette or saturation but whether the images are different from a POV view. The litmus test is if I align the two and flip between them I should see no perceptible motion) The other problematic issue is that the images are not always the same saturation or palette or quality but their content is basically the same but slightly different enough (<5%) to warrant scrutiny. Any suggestions or code would be greatly appreciated.
On a unrelated note, does anyone know of a package to automagically overlay and auto-align/calibrate similar images. I've been doing this manually with some packages and its quite a pain as some images have been cropped and others have more content in them. (not to mention correcting the aspect ratio in some instances as well) I've seen this done in extreme cases like some of the old bigfoot footage from the 60's where the subject was aligned into the frame by adjusting the pitch/rotation of the image. My case isn't that severe but there must be some method of edge detection to "lock" the images together. A lot of the lasso tools seem to have this functionality, can it be applied to the overlay as a point of comparison to the original? Are there commercial alternatives for this? -- View this message in context: http://www.nabble.com/Xor-Visual-diff---image-compare-vs-Beyond-Compare-tf4522622.html#a12901811 Sent from the Magick-users mailing list archive at Nabble.com. _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
