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:

Objective-C APIs can now express the “nullability” of parameters, return types, properties, variables, etc. For example, here is the expression of nullability for several UITableView APIs:

-(void)registerNib:(nonnull UINib *)nib forCellReuseIdentifier:(nonnull NSString *)identifier;
-(nullable UITableViewCell *)cellForRowAtIndexPath:(nonnull NSIndexPath)indexPath;
@property (nonatomic, readwrite, retain, nullable) UIView *backgroundView;

The nullability qualifiers affect the optionality of the Objective-C APIs when in Swift. Instead of being imported as implicitly-unwrapped optionals (e.g., UINib!), nonnull-qualified types are imported as non-optional (e.g., UINib) and nullable-qualified types are imported as optional (e.g., UITableViewCell?), so the above APIs will be seen in Swift as:

func registerNib(nib: UINib, forCellReuseIdentifier identifier: String)

// 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!
