The Big Blob » Moore Neighbor Contour Tracing Algorithm in C++

The Big Blob » Moore Neighbor Contour Tracing Algorithm in C++: "This post shows the implementation of Moore’s neighbor tracing algorithm in C++. This algorithm performs what is called contour tracing i.e.
tracing the borders or boundaries of, in this case, a binary image. The two images below illustrates what the algorithm does with a pure black and white/binary image."

Moore neighborhood - Wikipedia, the free encyclopedia

Moore neighborhood - Wikipedia, the free encyclopedia: "In cellular automata, the Moore neighborhood comprises the eight cells surrounding a central cell on a two-dimensional square lattice. The neighborhood is named after Edward F. Moore, a pioneer of cellular automata theory. It is one of the two most commonly used neighborhood types, the other one being the 4-cell von Neumann neighborhood. The well known Conway's Game of Life, for example, uses the Moore neighborhood. It is similar to the notion of 8-connected pixels in computer graphics."

Do Things that Don't Scale

Do Things that Don't Scale: "It's not enough just to do something extraordinary initially. You have to make an extraordinary effort initially. Any strategy that omits the effort—whether it's expecting a big launch to get you users, or a big partner—is ipso facto suspect."

Stop working (so hard) — I.M.H.O. — Medium

Stop working (so hard) — I.M.H.O. — Medium: "The idea that, without “hustle,” without throwing away nights and weekends, without putting your life on hold for your work, you’ll somehow be more successful, more productive, is ridiculous to me, yet continues to be pushed by participants in our industry left and right. This is, quite simply, insane.
