OpenCV Series #3: Working with Histograms
Histograms are kind of a big deal when it comes to digital image processing. By definition, a histogram is a bar graph that counts the occurrence of values within a certain range. It is widely used in statistics as well, with one example being the so-called Population Pyramid, which is a back-to-back histogram that displays the distribution of a population in all age groups
OpenCV Series #2: Labeling Image Features
After understanding how to access pixels and move them around, let's dive deeper into how we can apply that knowledge towards a technique called labeling.
Labeling is a general term that describes a technique where one would label each graphic element in an image individually in order to refer back to them later during processing. This technique has several applications, including, but not limited to, facial recognition, feature detection, object counting, and so on.
