Deep learning: survey of environmental and camera impacts on internet of things images

Abstract

Internet of Things (IoT) images are captivating growing attention because of their wide range of applications which requires visual analysis to drive automation. However, IoT images are predominantly captured from outdoor environments and thus are inherently impacted by the camera and environmental parameters which can adversely affect corresponding applications. Deep Learning (DL) has been widely adopted in the field of image processing and computer vision and can reduce the impact of these parameters on IoT images. Albeit, there are many DL-based techniques available in the current literature for analyzing and reducing the environmental and camera impacts on IoT images. However, to the best of our knowledge, no survey paper presents state-of-the-art DL-based approaches for this purpose. Motivated by this, for the first time, we present a Systematic Literature Review (SLR) of existing DL techniques available for analyzing and reducing environmental and camera lens impacts on IoT images. As part of this SLR, firstly, we reiterate and highlight the significance of IoT images in their respective applications. Secondly, we describe the DL techniques employed for assessing the environmental and camera lens distortion impacts on IoT images. Thirdly, we illustrate how DL can be effective in reducing the impact of environmental and camera lens distortion in IoT images. Finally, along with the critical reflection on the advantages and limitations of the techniques, we also present ways to address the research challenges of existing techniques and identify some further researches to advance the relevant research areas.

Analytical Method for Bridge Damage Using Deep Learning-Based Image Analysis Technology

“…Image quality can vary due to factors like weather conditions, lighting, and camera specifications. Poor-quality images may affect the accuracy of crack detection algorithms [3]. UAVs can capture a large volume of data, which may require significant storage and processing capabilities.…”

Impact of Traditional and Embedded Image Denoising on CNN-Based Deep Learning

“…When images are acquired, compressed, and transmitted, noise is inherently introduced by the environment, camera, and other factors, resulting in distortion and loss of information. With the presence of noise, image processing tasks, such as object recognition and segmentation, edge detection, and feature extraction are adversely affected [5]. This is because the contrast, edges, textures, object details, and quality of a noisy image are impacted, lowering the post-processing algorithm's performance [6].…”
