A beginners guide to AI: Computer vision and image recognition

Image recognition identifies which object or scene is in an image; object detection finds instances and locations of those objects in images. Recurrent Neural Networks (RNNs) are a type of neural network designed for sequential data analysis. They possess internal memory, allowing them to process sequences and capture temporal dependencies. In computer vision, RNNs find applications in tasks like image captioning, where context from previous words is crucial for generating meaningful descriptions. Variants like Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) were developed to mitigate these issues.

The sensitivity and specificity of the program for diagnosing patients with COVID-19 pneumonia were 90% and 96%, respectively [35]. In this research, we used the Mask R-CNN deep neural network model to extract lung contours and lesion locations from CT images to generate 3D lesion data, and to calculate quantification factors for COVID-19 [38]. The quantification parameters of CT samples obtained using the deep learning network showed a sensitivity of 96% and a specificity of 85% for detecting COVID-19. Additionally, we combined CT image characteristics with clinical parameters and applied an AI neural network to develop a prediction model for the severity of COVID-19. It must be noted that artificial intelligence is not the only technology in use for image recognition.

The magic lies in Machine Learning (ML) and Deep Learning (DL), two subsets of AI that breathe life into image recognition. While both fall under the umbrella of computer vision, they serve different purposes. Nanonets can have several applications within image recognition due to its focus on creating an automated workflow that simplifies the process of image annotation and labeling. Overall, the future of image recognition is very exciting, with numerous applications across various industries.

Modern object recognition applications include counting people in an event image or capturing products during the manufacturing process. It can also be used to detect dangerous objects in photos such as knives, guns or similar items. Fundamentally, an image recognition algorithm generally uses machine learning & deep learning models to identify objects by analyzing every individual pixel in an image. The image recognition algorithm is fed as many labeled images as possible in an attempt to train the model to recognize the objects in the images. CNNs, in particular, have become the go-to deep learning architecture for image recognition tasks. These models are designed to emulate the human visual system, enabling them to learn and recognize patterns and objects from raw pixel data.

Modern Deep Learning Algorithms

Returning to the example of the image of a road, it can have tags like ‘vehicles,’ ‘trees,’ ‘human,’ etc. The first steps toward what would later become image recognition technology happened in the late 1950s. An influential 1959 paper is often cited as the starting point to the basics of image recognition, though it had no direct relation to the algorithmic aspect of the development. The first step is to gather a sufficient amount of data that can include images, GIFs, videos, or live streams.

Image classification is a fundamental task in computer vision, and it is often used in applications such as object recognition, image search, and content-based image retrieval. By using various image recognition techniques it is possible to achieve incredible progress in many business fields. For example, image recognition can be used to detect defects of the goods or machinery, perform quality control, supervise inventory, identify damaged parts of vehicles and many more.

Deep learning techniques may sound complicated, but simple examples are a great way of getting started and learning more about the technology. Other organizations will be playing catch-up while those who have planned ahead gain market share over their competitors. Monitoring their animals has become a comfortable way for farmers to watch their cattle.
