Drawing from my firsthand experience in the tech world, I’ve always been intrigued by the vast potential of computer vision, especially its transformative power when infused with the Apple ecosystem — more precisely, iOS.
Apple, a trailblazer in innovation, has consistently integrated advanced features into its products, and its venture into computer vision is no exception. With its sophisticated hardware-software synergy and vast user base, the iOS platform offers a fertile ground for businesses to harness computer vision’s power, creating more intelligent, user-friendly, and ultimately transformative applications.
In this article, we will explore the intricacies of computer vision, its benefits, and real-world applications. Specifically, I’ll spotlight my journey of integrating it within the iOS app while working closely with one of DashDevs’ esteemed clients.
What is Computer Vision?
Computer Vision, frequently shortened to CV, emerges at the crossroads of artificial intelligence (AI) and image processing. The main goal is to equip machines with the capability to both analyze images and act upon visual information, akin to how humans employ their sight and cognitive faculties to comprehend visual signals from their surroundings.

Having been hands-on with various projects, I’ve come to appreciate the depth of what Computer Vision seeks to emulate — the very essence of human vision and sight. The field is vast, touching upon various facets like:
- Image Classification: Determining what an image contains. For example, discerning if a photograph contains a cat or a dog.
- Object Detection: Identifying multiple objects in an image and their locations.
- Facial Recognition: Recognizing and distinguishing individual faces.
- Scene Reconstruction: Creating a 3D model of a scene from a set of 2D images.
- Image Segmentation: Partitioning an image into multiple segments, each corresponding to a different object or part of an object.
If we are talking about the last point, image segmentation, there are two types of it — instance segmentation and semantic segmentation.
In instance segmentation, the goal is to distinguish individual instances of objects within the image. For instance, if an image has two cars, this process would separate each car into its own unique segment, even though both belong to the same object class of “cars.”
On the other hand, semantic segmentation categorizes every pixel in the image based on the class or category to which they belong, such as ‘car,’ ’tree,’ ‘house,’ and so on. Unlike instance segmentation, semantic segmentation doesn’t differentiate between individual instances of the same class. Therefore, in the case of an image with two cars, semantic segmentation would label all pixels corresponding to both cars simply as “car” without distinguishing between the two vehicles.
How Computer Vision Systems Perceive and Interpret Visual Information
Contrary to our organic, holistic way of viewing the world, computers perceive things differently. Instead of a cohesive scene, they see a mosaic of pixel values. Having been a part of numerous projects, I’ve watched in awe as machines, through ingenious algorithms, discern patterns, contours, hues, and textures.
For instance, imagine teaching a computer to detect the edge of a table. To us, it’s an obvious boundary, but to a computer? It’s a puzzle solved using edge detection algorithms, discerning one item from another, pixel by pixel.
Apple, with its constant endeavor to simplify complex technologies for developers, has rolled out a Vision framework to facilitate the integration of CV into iOS apps. Whether you’re looking to detect faces, read barcodes, or track objects in videos, the Vision framework provides tools and APIs to make these tasks simpler for developers.
