Hello, I'm interested in the project to develop a test framework and was trying to get a better idea of what the image comparison between the baseline and test glyph/image would involve.
As I see it, there are many different ways to go with the comparison. A basic method might be comparing pixel-by-pixel, using for example the RGB or HSV values to look for and quantify possible differences. A more interesting method I came across included computing color/brightness histograms for each image and combining this with a measure of the texture of the image by performing edge detection on the images. I was wondering what direction you wanted to go with the method of the comparison. Is the goal to get a fast and simple measure of the differences between images/glyphs, with any basic method as mentioned above? Do we want a more robust method that works with rotations or scaling differences? I appreciate any guidance, Regards, Arvinder Bhathal (arv) (Studying Computer Science at Western University in London, Canada) _______________________________________________ Freetype-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/freetype-devel
