Mastering OpenCV 4 with Python

Main problems in image processing

The first concept to introduce is related to images, which can be seen as a two-dimensional (2D) view of a 3D world. A digital image is a numeric representation, normally binary, of a 2D image as a finite set of digital values, which are called pixels (the concept of a pixel will be explained in detail in the Concepts of pixels, colors, channels, images, and color spaces section). Therefore, the goal of computer vision is to transform this 2D data into the following:

• A new representation (for example, a new image)
• A decision (for example, perform a concrete task)
• A new result (for example, correct classification of the image)
• Some useful information extraction (for example, object detection)
