I've been interested in computer vision for a long time, but I haven't had any free time to make any progress until this holiday season. Over Christmas and the New Years I experimented with various methodologies in OpenCV to detect road signs and other objects of interest to OpenStreetMap. After some failed experiments with thresholding and feature detection, the excellent /r/computervision suggested using the dlib C++ module because it has more consistently-good documentation and the pre-built tools are faster.

After a day or two figuring out how to compile the examples, I finally made some progress:

Compiling dlib C++ on a Mac with Homebrew

1. Clone dlib from Github to your local machine:

    uint16_t fNumTables;
    uint16_t fSearchRange;
    uint16_t fEntrySelector;
    uint16_t fRangeShift;
}FontHeader;

typedef struct TableEntry {
    uint32_t fTag;

// warping hexagons, WIP. @psonice_cw
// I'm sure there's a less fugly way of making a hexagonal grid, but hey :)

//  Maybe - Try this...

// Simplify!
