Let’s look at the example image in Figure 1: Figure 1: This image is 600 pixels wide and 450 pixels tall for a total of 600 x 450 = 270,000 pixels. If we think of an image as a grid, each square in the grid contains a single pixel. Normally, a pixel is considered the “color” or the “intensity” of light that appears in a given place in our image. There is no finer granularity than the pixel. Pixels are the raw building blocks of an image. We’ll wrap up this tutorial with a discussion of our results. As the name suggests, this allows us to access and manipulate pixels using OpenCV. With our project directory structure reviewed, we’ll implement a Python script, opencv_getting_setting.py. We’ll also review the image coordinate system in OpenCV, including the proper notation to access individual pixel values.įrom there, we’ll configure our development environment and review our project directory structure. In the first part of this tutorial, you will discover what pixels are (i.e., the building blocks of an image). Looking for the source code to this post?
