What You Need To Know About Image Data Augmentation for Computer Vision

Last Updated on December 28, 2022 by Hammad Hassan

The rise of computer vision can be attributed to the success of deep learning techniques such as CNN. However, these methods are heavily reliant on training data to avoid overfitting or poor model performance. This is a major issue that can be solved by collecting more training data. In most cases, collecting enough training data is very expensive and challenging.

Data Augmentation- What is it?

Data augmentation techniques are used to improve the quality of training datasets for deep learning models. They can also help prevent overfitting and improve performance. There are different types of data augmentation techniques that are popular. Some of these techniques include kernel filtering, feature space augmentation, random erasing, and geometric transformations. They can also be used to improve the performance of generative adversarial networks.

Difference between Machine Vision and Computer Vision

Now, let’s discuss machine vision vs computer vision. The idea of machines being able to act and see for us has been presented in various forms of science fiction for decades. Machine vision was first introduced in the field of engineering, which involves using existing technologies to visualize steps in a production line. This technology can help manufacturers identify potential defects in their products before they are sold.

Since the inception of computer vision, machine vision has been advancing into the future. In terms of its body, computer vision refers to the nervous system, the brain, the retina, and the optic nerve. A machine vision system uses cameras to view an image and then interprets the data it generates.

Although computer vision can be used alone, it requires the necessary software and hardware to operate properly. In terms of its core capabilities, a machine vision system cannot operate without these two components. A computer vision system can take an image from a variety of sources, such as infrared sensors, cameras, and motion detectors.

Due to the increasing number of cameras and the complexity of the image processing process, computer vision has been able to process moving and 3D images. Its sophisticated operations allow it to analyze and interpret the data it generates. As computer vision technology continues to improve, its applications can be expected to expand. For instance, in the future, autonomous vehicles could be equipped with braking systems that can recognize and respond to complex situations.

Deep Fitting Reduces Overfitting

The advancements in deep learning have been mainly due to the increasing number of deep network architectures and the ability to access large amounts of data. These capabilities have been able to perform various tasks in computer vision, such as object detection and image classification.

One of the most challenging aspects of deep learning is the generalizability of its models. This is because, when evaluating a model, it compares its performance against data that it has previously seen.

A poor generalizability model leads to overfitting, which is a problem that occurs when a model performs poorly in testing. You can reduce overfitting by implementing data augmentation, which is a method that allows a model to collect more data points.

Bigger Data Sets Are the Best

Although large datasets can improve the performance of deep learning models, assembling them efficiently can be a challenge. This is because, in most cases, it requires the manual handling of data labels and images.

Due to the limited number of data points that can be collected with small datasets, the development of deep learning models in real-life applications is often hindered by the lack of data. Big data has been able to greatly improve the performance of medical image analysis systems by allowing them to perform complex tasks such as skin lesion classification.

Getting the necessary data collected for training computer vision systems is often an expensive process. This is because of the various factors that affect the quality of the data, such as privacy requirements, the rarity of events, and the cost of recording visual data.

Challenges of Data Collecting

To develop better computer vision systems, the community has created large datasets that are capable of handling large amounts of data. These include the PASCAL VOC, MS COCO, and SUN RGB-D datasets. Unfortunately, not every scenario can be covered by these datasets. Therefore, developing deep learning models in real-world applications requires the continuous collection and analysis of data.

In real-world applications, the complexity of the tasks that are performed by computer vision systems increases significantly. This is because the data collected by these systems often requires the development of complex models.

The increasing complexity of the tasks that are performed by computer vision systems also makes data collection more challenging. Although some scenarios may not occur in real-world situations, correctly handling them is very important.

Getting the necessary training data is often an expensive process. In most cases, the process involves the use of various hardware, software tools, and cameras. Usually, experts in the field of computer vision will be involved in the collection process.

The increasing complexity of the task of image annotation also makes it more expensive to create the ground-truth data needed for training. This process can be caused by the shift from labeling frames to identifying objects, key points, and pixels in the image.

Bottom Line

To train deep learning models, the systems often require a large amount of training data. Data augmentation techniques can be used to improve the performance of these systems by artificially adding value to the training set.
