blMemStorage — A simple data structure to wrap OpenCV’s CvMemStorage with shared_ptr

Introduction As part of the blImageAPI series that we’re running, in this short article, we present a simple data structure used to wrap OpenCV’s CvMemStorage with boost::shared_ptr. The use of boost::shared_ptr allows for automatic garbage collection and lets us check the validity of pointers, which will save us from those horrific opencv…

blImageAPI — Convert an opencv image from RGB to HSV color space no matter what the depth is

Introduction When we start playing with images, dealing with colors becomes an inevitibility. Over the past hundreds of years, different ways to look at colors have evolved in the form of color spaces. These color spaces help us conceptualize colors in advantageous ways. In this article I present a couple…
