Lecturas Indispensables Operations with images Accessing pixel intensity values In order to get pixel intensity value, you have to know the type of an image and the number of channels. Here is an example for a single channel grey scale image (type 8UC1) and pixel coordinates x and y: Scalar intensity =<uchar>(y, x); intensity.val[0] contains a value from 0 to 255. Scalar intensity =<uchar>(Point(x, y)); Now let us consider a 3 channel image with BGR color ordering (the default format returned by imread): Vec3b intensity =<Vec3b>(y, x);uchar blue = intensity.val[0];uchar green = intensity.val[1];uchar red = intensity.val[2]; You can use the same method for floating-point images (for example, you can get such an image by running Sobel on a 3 channel image): Vec3f intensity =<Vec3f>(y, x);float blue = intensity.val[0];float green = intensity.val[1];float red = intensity.val[2]; The same method can be used to change pixel intensities:<uchar>(y, x) = 128; Point2f point =<Point2f>(i, 0);

The Ramer-Douglas-Peucker Polygon Simplification Algorithm Here is how it roughly works: 0. Start with a polygon. 1. 2. 3. The idea with the algorithm is that we can give it an input like the one to the left and get an output like the one to the right: This gives us a lot of possibilities; it can reconstruct the original representation of a polygon and it can provide us with compression of the data. I’ve added this algorithm to Farseer Physics Engine 3.0.

Images of Liberty and Power Art of the Levellers In the course of putting together a multi-volume collection of over 240 Leveller Tracts I came across some very interesting title pages which used typography and occasionally woodcuts to add graphical force to the political and economic arguments being made by the authors.
