Deep Learning In Computer Vision



Deep learning took this one step further by creating layer-based neural networks where levels of solution-based networks could essentially create an emergent problem-solving engine. For example, a deep-learning brain could have layers where simple pattern-recognition approaches could come together to power complex tasks like facial recognition in images.




Deep Learning in Computer Vision



Enter computer vision. Computer vision is an application of machine learning and artificial intelligence that takes information from digital images and videos and makes meaningful decisions based on that information.


Essentially, computer vision uses CNNs and deep learning to perform high-speed, high-volume unsupervised learning on visual information to train machine learning systems to interpret data in a way somewhat resembling how a human eye works.


Computer vision is a subset of machine learning. After interest in artificial intelligence and machine learning research waned in the mid-1980s to the mid-1990s, much of the development in the field fragmented into subfields like natural language processing, image recognition, and robotics.


Furthermore, computer vision could be defined as a subset of deep learning. Instead of processing simulated data or statistics, however, computer vision breaks down and interprets visual information.


On the other hand, computer vision systems require visual information to learn and function. Computer vision systems will combine the machine learning approaches previously discussed with hardware like cameras, optical sensors, etc.. This approach does provide some limitations, including challenges with hardware and how to convert images into helpful data structures for machine learning.


Computer vision needs lots of data. It runs analyses of data over and over until it discerns distinctions and ultimately recognize images. For example, to train a computer to recognize automobile tires, it needs to be fed vast quantities of tire images and tire-related items to learn the differences and recognize a tire, especially one with no defects.


At about the same time, the first computer image scanning technology was developed, enabling computers to digitize and acquire images. Another milestone was reached in 1963 when computers were able to transform two-dimensional images into three-dimensional forms. In the 1960s, AI emerged as an academic field of study, and it also marked the beginning of the AI quest to solve the human vision problem.


In 1982, neuroscientist David Marr established that vision works hierarchically and introduced algorithms for machines to detect edges, corners, curves and similar basic shapes. Concurrently, computer scientist Kunihiko Fukushima developed a network of cells that could recognize patterns. The network, called the Neocognitron, included convolutional layers in a neural network.


By 2000, the focus of study was on object recognition, and by 2001, the first real-time face recognition applications appeared. Standardization of how visual data sets are tagged and annotated emerged through the 2000s. In 2010, the ImageNet data set became available. It contained millions of tagged images across a thousand object classes and provides a foundation for CNNs and deep learning models used today. In 2012, a team from the University of Toronto entered a CNN into an image recognition contest. The model, called AlexNet, significantly reduced the error rate for image recognition. After this breakthrough, error rates have fallen to just a few percent.(5)


Semantic segmentation, object detection, and image recognition. Computer vision applications integrated with deep learning provide advanced algorithms with deep learning accuracy. MATLAB provides an environment to design, create, and integrate deep learning models with computer vision applications.

Machine learning in Computer Vision is a coupled breakthrough that continues to fuel the curiosity of startup founders, computer scientists, and engineers for decades. It targets different application domains to solve critical real-life problems basing its algorithm from the human biological vision.


These real-life problems keep us at bay as it aims to provide solutions using computer vision. However, computer vision alone is already a complex field. For example, the certainty of algorithms to use is already a huge challenge and so is finding the right computer vision resources.


Computer vision is the process of understanding digital images and videos using computers. It seeks to automate tasks that human vision can achieve. This involves methods of acquiring, processing, analyzing, and understanding digital images, and extraction of data from the real world to produce information. It also has sub-domains such as object recognition, video tracking, and motion estimation, thus having applications in medicine, navigation, and object modeling.


To put it simply, computer vision works with a device using a camera to take pictures or videos, then perform analysis. The goal of computer vision is to understand the content of digital images and videos. Furthermore, extract something useful and meaningful from these images and videos to solve varied problems. Such examples are systems that can check if there is any food inside the refrigerator, checking the health status of ornamental plants, and complex processes such as disaster retrieval operation.


Machine learning is the study of algorithms and statistical models, which is a subset of artificial intelligence. Systems use it to perform a task without explicit instructions and instead rely on patterns and inference. Thus, it applies to computer vision, software engineering, and pattern recognition.


Machine learning is done by computers with minimal assistance from software programmers. It uses data to make decisions and allows it to be used in interesting ways in a wide variety of industries. It can be classified as supervised learning, semi-supervised learning, and unsupervised learning.


Supervised learning is a machine learning task that maps each input object to the desired output value. The computer is trained to associate an object with the desired output. It has a wide range of algorithms for different supervised learning problems.


Machine learning and computer vision are two fields that have become closely related to one another. Machine learning has improved computer vision about recognition and tracking. It offers effective methods for acquisition, image processing, and object focus which are used in computer vision. In turn, computer vision has broadened the scope of machine learning. It involves a digital image or video, a sensing device, an interpreting device, and the interpretation stage. Machine learning is used in computer vision in the interpreting device and interpretation stage.


Relatively, machine learning is the broader field, and this is evident in the algorithms that can be applied to other fields. An example is the analysis of a digital recording, which is done with the use of machine learning principles. Computer vision, on the other hand, primarily deals with digital images and videos. Also, it has relationships in the fields of information engineering, physics, neurobiology, and signal processing.


The obstacle faced by developers and entrepreneurs is the huge gap between computer vision and biological vision. The fields most closely related to computer vision are image processing and image analysis. However, it deserves another interesting article to cite its relationship and differences. Also, the lack of knowledge about the main goal of machine learning in a particular project is a huge disruption among entrepreneurs.

Despite the clamor of AI, machine learning, and computer vision, it was clear to us, albeit accurate, that the computer vision is still behind the human biological vision. This is the reality faced by both entrepreneurs and developers. Aside from the fact that engaging in this kind of venture introduced tantamount of expenses, the limitations of general learning algorithms, and resource scarcity.


There are two major types of uncertainty one can model. Aleatoric uncertainty captures noise inherent in the observations. On the other hand, epistemic uncertainty accounts for uncertainty in the model - uncertainty which can be explained away given enough data. Traditionally it has been difficult to model epistemic uncertainty in computer vision, but with new Bayesian deep learning tools this is now possible. We study the benefits of modeling epistemic vs. aleatoric uncertainty in Bayesian deep learning models for vision tasks. For this we present a Bayesian deep learning framework combining input-dependent aleatoric uncertainty together with epistemic uncertainty. We study models under the framework with per-pixel semantic segmentation and depth regression tasks. Further, our explicit uncertainty formulation leads to new loss functions for these tasks, which can be interpreted as learned attenuation. This makes the loss more robust to noisy data, also giving new state-of-the-art results on segmentation and depth regression benchmarks. 041b061a72
