WebChain code is a method of describing the shape of the boundary of an object in an image, we use the term chain code although its proper name is Freeman chain code. The idea is to traverse the boundary of the object, and for every new pixel, transcript the direction we traveled to reach this object. WebProject Description. Write a function to find an approximation to images as vector graphics (effectively: "convert GIF to SVG'). Flags may be a helpful example to consider. There will be a tradeoff between "fitting' the image, and having a simple "model' in terms of vector graphics. Category: Algorithms, Artificial Intelligence.

WebCHAIN_APPROX_NONE: The outline is output in the form of Freeman chain code, and all other methods output polygons (sequence of vertices). CHAIN_APPROX_SIMPLE (most commonly used): Compress the horizontal, vertical and diagonal parts, that is, the function only retains their end parts. An example of the following picture: Find and draw outlines
