I couldn't find any mid-range values in either image.</p> <p>Are you sure you aren't saving these with JPEG compression and seeing compression artifacts? Have you somehow resized the resulting image, where interpolation might be blurring some of the sharp white lines? If you're capturing raw data, are you capturing at the exact same size as the output image from the Canny filter?</p> pubDate Mon, 04 Jun 2012 15:24:34 +0000 dc:creator Brad Larson guid false comment 1438 at http://www.sunsetlakesoftware.com
