C++ implementation of the Connected Component Labeling method using the Disjoint Set data structure

In the post before last we discussed using cvBlobsLib as a tool for blob extraction. We're going to revisit the extraction theme and look at a C++ implementation of the Connected Component Labeling method, but before we do that we're going to look at an implementation of the Disjoint Set data structure that will provide …

Detecting blobs with cvBlobsLib and tracking blob events across frames

In my previous post we discussed using OpenCV to prepare images for blob detection. We will build upon that foundation by using cvBlobsLib to process our binary images for blobs. A C++ vector object will store our blobs, and the center points and axis-aligned bounding boxes will be computed for each element in this vector. …
