What you need is an image similarity measure. This paper deals with that, but you'll have to implement by yourself. Don't know wheter their results are accurate, since I can't see the images they used. This behind paywall paper also deals with that using a technique I used before, called NCD (normalized compression distance). The output of such measure is ...


The computer vision research community frequently uses the PSNR (peak signal to noise ratio) when comparing images, for example to assess how good a particular compression or image reconstruction algorithm is. The wikipedia page describes how to calculate it: It's a mathematical score based on the ...


You could use Photoshop and layers to view a "difference" between them. I'm aware of a diff Mac app that does this with images: Kaleidoscope's image scope sounds like what you want.


You are using an environment without color calibration. Furthermore, the JPEG does not seem to have embedded color information. I sometimes have the same. Edit a picture in Photoshop - nice. (Photo has embedded color profile, Photoshop can handle that). Then save in JPEG with conversion to sRGB, then preview it - super ugly. (The previewer does not handle ...


At first you should make sure that your camera can take Panorama (360°) Photos. After that you can edit your photos and put them beside each other by Special Softwares on Mac or Windows . Good Luck ;)


if you look in the sips-Manpage there is no way to force exporting of 8 or 16 bit. That's the answer: there is no way to do this with sips. Is there any reason for using sips, instead of Lightroom or Aperture, which have great batch modes too?


Well, let's say camera A is the Velvia, camera B is your Nikon. Camera A converts physical colors to virtual colors ("pixels") using funcA. Camera B converts physical colors to virtual colors (pixels) using funcB. Establish an ICC profile (ICCA) that converts the pixel color to viewing environment color. Establish an ICC profile (ICCB) that converts the ...


Symbian? Have you tried Photo Effect? Probably your best bet is to find a way to install Android on that smartphone :P For Android I highly recommend Pixlr Express - which is free, simple to use, and does everything you need.


The act of adding pixels to make the image larger (without adding extra information (this is an important point)) is a basic function of any image processor. There are any number of applications that can do this, however NO image processors can add information to your image, at least not automatically. They can use the information that is already there to ...


You can print a 461 by 491 image at whatever size you want, but it isn't going to have any more detail than it has right now. You can't invent detail, you can create new pixels that will make a smooth shading to make it seem less pixely, but it will then just seem more blurry. Unfortunately, at that low of resolution, you really are not going to be able to ...


Short answer: Oh, boy... Long answer: The way exists, of course. However, the quality most probably will be very low because the difference in dimensions are too big. I assume that "print it in a regular image size" from your question talks about an image somewhere around 6 MPixels, which is rather conservative. Perhaps other would say 8 Mpixels. Anyway ...
