NVIDIA® software enables the end-to-end computer vision (CV) workflow—from model development to deployment—for individual developers, higher education and research, and enterprises.
Computer vision is a field of technology that enables devices like smart cameras to acquire, process, analyze, and interpret images and videos. It can be understood across domains based on type and technique.
Traditional computer vision, also referred to as non-deep learning-based computer vision or image processing, performs a specific task based on hard-coded instructions. For instance, image processing might be used to mirror an image or reduce noise in a video. AI-based computer vision, or vision AI, relies on algorithms that have been trained on visual data to accomplish a specific task. For example, the driver assistance system on an autonomous vehicle designed with CV algorithms uses cameras and other sensors to not only display, but to perceive what’s in front of and behind it to identify and classify into regions or points of interest within an image frame. In this case, computer vision has a safety application—helping the vehicle operator to navigate around road debris, other vehicles, animals, and people. Similarly, farmers might rely on CV-enabled devices to automatically identify weeds and where crops are growing well over a large field to increase yield. CV tasks like these are based on artificial intelligence and, more specifically, deep learning, a type of machine learning patterned after the brain.
Regardless of type, computer vision models let devices perform tasks in real-time that mimic human-like vision capabilities.
Computer vision techniques
Most techniques begin with a model–or a mathematical algorithm–that’s been trained with volumes of data to accomplish a specific task. Some of the common techniques include:
Classification involves identifying what object is in an image or video frame. Classification models are usually trained with a large dataset to identify simple objects like dogs, cats, chairs, or very specific ones like the type of vehicles in a road scene. The quality of the classification output depends on the training data used. The more the quantity and diversity of the training data, the higher the degree of precision.
Detection involves locating and localizing an object or multiple objects within an image or a video frame. The algorithm outputs a rectangular bounding box around the detected object to indicate its location in the image. Object detectors may be trained to detect cars, road signs, people, or other objects of interest within an image or a video frame.
Segmentation involves locating objects or regions of interest precisely in an image by assigning a label to every pixel in an image. This way, pixels with the same label share similar characteristics, such as color, or texture. Segmentation models are very commonly used in medical imaging for performing tasks like automatically detecting tumors in Magnetic Resonance Imaging (MRI) scans.
Neural Radiance Fields (NeRF)
NeRF involves creating three dimensional (3D) content from inferring between two or more two dimensional (2D) image inputs. It creates novel views and 3D scenes based on inferring from a set of images. NeRF networks, like Generative Adversarial Networks (GANs), can be used to generate synthetic data.
The artificial intelligence-based computer vision workflow
The computer vision workflow is highly dependent on the task, model, and data. A typical, simplified Artificial Intelligence (AI)-based end-to-end CV workflow involves three (3) key stages—Model and Data Selection, Training and Testing/Evaluation, and Deployment and Execution.
Let’s look at these stages using the CV detection technique to identify a dog (classification and segmentation-based techniques would follow an identical workflow).
Finding Fido: Developing an AI-based object-detection cv workflow
Challenge: You want to build software for a monitoring system that automatically detects when your dog arrives at or leaves through the backdoor.
Model and Data Selection
Select an object-detection model. Collect photos of your dog (let's call him Fido) that you can use to train and fine-tune your model to recognize him.
Training and Testing/Evaluation
Train and test your model using different photos of Fido to affirm the model's accuracy in detecting him.
Deployment and Execution
Deploy the trained model to hardware to monitor and detect the next time Fido leaves the house using an installed camera. Below, a high-level diagram summarizes the AI-based CV solution.
NVIDIA enables the end-to-end CV workflow, providing not only AI-based pretrained models, but also tools for training and testing/evaluation and software application frameworks for deployment and execution. Learn more below about how NVIDIA enables every stage of CV development.
Get started with pretrained models for computer vision
Developing models for these techniques on your own would require a lot of training data, time, and expertise. Here’s the good news–you don’t have to be an expert to get started. NVIDIA hosts a number of pretrained models, already built and ready-to-use, to start developing your own CV solutions. Start with NGC,--our (GPU) accelerated software hub–to learn about computer vision models and resources, as well as other deep learning-based speech and natural language processing use cases and application frameworks.
