# blob - a 8-neighbour connected components labelling and contours extractor.

See [blob.h](blob.h) for a complete documentation.

## Reference ##

"A linear-time component-labeling algorithm using contour tracing technique"

 by Fu Chang, Chun-Jen Chen, and Chi-Jen Lu.

## Example ##

The [test](test) directory contains the source code of a small program that generates an image of the label buffer as long as a JSON file and a GNUplot data file containing the set of extracted contours.

#### source



#### label

 

#### contours

## Build ##

A CMake configuration file is provided in order to build a static library and the associated documentation.

A typical usage of CMake may be:

```bash

mkdir build

cd build

cmake ..

cmake --build .

```

On a Linux system, the Makefile will generate a static library `libblob.a`. 

`cmake --build . --target doc` will generate the documentation with [DoxyGen](http://www.stack.nl/~dimitri/doxygen/).
