Trace perimeter of binary image with line segments (bwperimtrace)
Lines surrounding contiguous regions in an image can be extracted using MATLAB's built-in contour/contourc functions, but these functions perform linear interpolation between pixels leading to 'cut corners'. bwperim from the imaging toolbox will trace boundaries without interpolation, but only provides its result as a pixel map. This function, bwperimtrace, instead outputs line segments that entirely contain all non-zero pixels in the input image. The package also includes contourc4, a replacement for contourc, which doesn't perform any interpolation between pixels.
