Understanding Computer Vision

What is Computer Vision?

Computer vision is a field of artificial intelligence that allows machines to perceive and interpret visual information from the world. Computer vision helps machines recognise stimuli and classify objects. It also helps machines find important information in images and videos. These processes work in a way that mimics how humans see. At the time, computer vision mostly used rule-based algorithms and feature extraction techniques. Today, deep learning models, neural networks, and GPU acceleration help machines. They reach superhuman accuracy in object tracking, image classification, and video analysis.

What is the Process of Computer Vision?

Current practices in computer vision and computer vision deep learning are very heavily reliant on deep learning (CNNs and deep neural networks specifically). The general workflow involves:

• DataSet: Datasets such as ImageNet, CIFAR, and Imagenette are popular datasets for training models. The nice thing is that there are some libraries, such as OpenCV and various Keras preprocessing layers that can help pre-process those images for a neural network.
• Neural Network Architecture: This is the step of designing our own Artificial Neural Networks, the model can also build off pretrained models like ResNet50, InceptionV3, YOLOv8, Faster R-CNN or Mask R-CNN for a specific goal.

Training and optimisation use optimisers like Adam. Data augmentation happens through Batch Normalisation. Distributed training on GPUs or TPUs improves GPU use. These are common methods.

Deployment: Integrate models into cloud-based platforms such as Google Cloud, deploying models to production with either Docker, FastAPI, TorchServe, or TensorFlow Serving. 

Techniques such as PyTorch's Eager Execution or Dynamic Computational Graph allow us to do more both in terms of using our models and operating much quickly. TensorFlow offers Static Computational Graphs for similar reasons. 

Most Popular Computer Vision Applications You Should Know

• Healthcare: AI-enabled diagnostics that help identify anomalies in X-rays or MRIs with its use of object detection models.
• Automotive: Autonomous driving applications rely on the need for image recognition and object detection. 
• Retail: Inventory tracking and assessing consumer behaviour, as well as automating checkouts. Facial recognition models and surveillance systems analyse data in real time. They help with situational awareness and real-time monitoring. 

According to Fortune Business Insights, the computer vision market will grow tremendously into a $17 billion industry. AI-optimised solutions will become more commonplace in operational work. 

An Introduction to PyTorch  

What is PyTorch? How It Powers Computer Vision and NLP

PyTorch is an open-source deep learning framework developed by Meta AI, formerly known as Facebook AI Research Lab (FAIR). It is one of the most widely used frameworks in research. It is popular due to its design and features such as Dynamic Computation Graphs, Eager Execution, and native Python programming language compatibility. Its key features include:

• Dynamic Computational Graphs: Models can change based on the operations when training.
• AutoGrad: Simplicity in computing gradients of deep learning models.
• GPU Support (CUDA): Fast computation for deep neural networks.
• PyTorch Lightning: A higher-level interface for scalable distributed computing, building, and training.

There are also several high-level packages available: TorchVision, TorchText, TorchElastic, and TorchServe for computer vision, natural language processing, distributed training, and deploying to production respectively.

Installing PyTorch for development can be done using pip or conda - either CPU only or GPU accelerated (CUDA).
