Have you ever wondered how computers process images? Well, one of the simplest and most powerful types of images used in computer vision is the binary image. In this article, we’ll explore the fascinating world of binary images and how they can be leveraged in various domains.

What Are Binary Images?
Binary images are images that consist of only two values: 0 or 1. They are incredibly easy to process, store, and analyze. The process of creating a binary image starts with a gray-level image, which represents the brightness of each pixel. By applying a predetermined threshold to this gray-level image, we can obtain a binary image. The threshold can be automatically computed or set by the user.
Unleashing the Power of Binary Images
Binary images are more than just simple representations. They hold tremendous potential in various domains. For example, in fingerprint analysis, binary images allow us to focus on the curves and ridges of the fingerprints, aiding in identification. Visual codes, such as QR codes, also rely on binary images, with the corners of the pattern used to determine the bits encoded within.
But the utility of binary images extends beyond these examples. In the field of medical imaging, binary images help analyze the structure of bones and other three-dimensional objects. By capturing two-dimensional images of objects in stable configurations and converting them into binary images, we can recognize and study these objects with relative ease.
Harnessing the Magic of Backlighting
While binary images offer unparalleled convenience, creating them from complex three-dimensional objects can be challenging. Objects with shading, highlights, and varying colors pose difficulties for simple thresholding. To overcome this, scientists have developed specialized imaging systems that employ backlighting.
By placing objects on a backlighting system and capturing an image from the top, these systems can directly generate nearly perfect binary images. The backlighting eliminates shading and highlights, providing a clean silhouette of the objects. This innovative technique simplifies the processing of binary images, making them even more versatile.
The Power of Geometric Properties
Once we have binary images, we can extract valuable information through geometric computations. We can determine the position and properties of objects in the image while remaining invariant to translation and rotation. This allows us to distinguish objects and facilitate their recognition.
Segmentation: Unraveling the Image
In many cases, binary images may contain multiple objects within a single image. To analyze these objects individually, segmentation is required. Segmentation involves labeling each object in the binary image, allowing us to compute their geometric properties accurately. Luckily, there are efficient algorithms available for quick and reliable segmentation.
Iterative Modification: The Art of Preservation
Iterative modification is a fascinating process of refining binary images. One such modification involves thinning an object to reveal its skeleton. By applying a simple algorithm to each pixel, we iteratively modify the image, preserving the object’s structure while eliminating unnecessary details. The goal is to create a skeleton image that accurately represents the object.
Conclusion
Binary images, with their simplicity and efficiency, have revolutionized the field of computer vision. From fingerprint analysis to medical imaging, they have proven to be indispensable tools. By understanding the power of binary images and leveraging their geometric properties and segmentation algorithms, we can unlock a world of possibilities in image processing.
