Ballast has a significant impact on track performance, and the evaluation of ballast condition is crucial for safe railroad operations. this paper focuses on a Ballast Scanning Vehicle (BSV) recently developed for automating ballast inspection using a deep learning-based, computer vision approach. Traditional evaluation methods, e.g., visual inspection or ballast sampling followed by sieve analysis, are subjective and labor-intensive. Furthermore, ballast samples collected from a single location/depth may not be representative of accurately revealing variations of degradation and ballast condition along the track. In contrast, the BSV employs three image acquisition devices to continuously capture high-quality scans of ballast cut sections, enabling accurate and in-depth evaluation of continuous sections of the track. the deep-learning framework was trained to process acquired ballast scans, generating image-based metrics including percent degraded segments (PDS), fouling index (FI) estimates, and in-service ballast gradations. the accompanying user-friendly graphical interface integrates all data processing algorithms and provides comprehensive visualizations of results. Field data was collected using the BSV, from cut trenches opened using a ballast regulator, along the High Tonnage Loop (HTL) at the Transportation Technology Center (TTC) in the U.S. the FI and gradations from the BSV were compared to laboratory sieve analyses and Ground Penetrating Radar (GPR) data. Additional laboratory tests with various fouling conditions were conducted to validate the deep learning algorithms and clarify any differences between sieving results and algorithm estimates possibly attributed to sampling issues. this field deployment demonstrated that the BSV could accurately evaluate ballast conditions close to real time, thus making it a robust system for quantifying ballast degradation.

A group of eye conditions known as glaucoma impair the optic nerve, which is in charge of sending visual data from the eye to the brain. Glaucoma impacts 3.54% of adults aged 40 to 80 around the world. Early detection of glaucoma is crucial as it can prevent total optic nerve damage, which would cause irreversible vision loss. It is possible for specialists to diagnose glaucoma medically, but treatment options are either expensive or time-consuming and requires ongoing care from medical professionals. there have been numerous initiatives at streamlining all components of the glaucoma categorization process, however these models are challenging for users to comprehend the key predictors, resulting in them being unreliable for use by medical experts. the study uses eye fundus images to classify glaucoma patients using three distinct Deep Learning techniques: Convolutional neural network, Visual Geometry Group 16 (VGG16), and Global Context Network (GC-Net). In addition, several data pre-processing techniques are used to avoid overfitting and achieve high accuracy. this research compares and analyses the performance of various architectures using the aforementioned techniques. the CNN model had the best accuracy of 83% when in contrast to the other deep learning models.

Lychee and longan are important economic crops in South China. Fast identifying and acquiring their planting areas are important tasks. However, lychee trees and longan trees have similar appearances. So, they have similar spectral features. therefore, obtaining the planting area of these trees from a remote sensing image becomes a challenge. Furthermore, unlike lychee, the planting area of longan in Guangdong province is too small to be identified. therefore, spatial and spectral resolution may become important factors for the classification. To evaluate the influence of spatial and spectral resolution on lychee and longan classification, this paper compares different kinds of representative remote sensing data sources, including Sentinel-2(high spatial resolution, multispectral image), Zhuhai-1(high spatial resolution, hyperspectral image), Gaofen-5(low spatial resolution, hyperspectral image), Ziyuan-1 02D (low spatial resolution, hyperspectral image), as well as the fused image of GF-5 with Sentinel-2. We aim at finding which spatial and spectral resolution can be suitable for classification. We combine a hierarchical classifier and convolutional neural networks (CNNs) to classify the classes. the hierarchical classifier classifies the land use classes and the combined class of lychee and longan at the first level. And then it classifies lychee and longan from the combined class at the second level. the CNN is used as a base classifier in the hierarchical classifier. three branches, i.e. spatial feature, spectral feature, and the joint of spatial and spectral feature branches, are the backbone of the network. 1D, 2D and 3D convolutional layers are designed to extract the spectral features, the spatial features and the joint features in the above branches, respectively. the experimental results show that spectral resolution is the most important factor for the lychee and longan classification, while spatial resolution cannot be ignored since longan occupies small
