Accurate positioning of screen primitives is crucial in the machine vision-based automatic detection of intelligent water meter LCD screens. Detecting edge details of the LCD screen using the A component of the LAB color space improves the accuracy of LCD screen area positioning. This approach reduces background interference from Gaussian noise, non-uniform lighting, specular reflection, and local highlights. This study proposes a technique that combines NL-means and Sauvola local threshold segmentation methods to locate LCD screen areas and graphics elements. The experimental results indicate that this technique satisfies the defect detection criteria for smart water meter LCD screens set by the enterprise. The LCD screen detection tool extracted a smart water meter LCD screen image with 98.4% accuracy in LCD screen element positioning. Compared to the median filter method, this represents a significant improvement, and the combination with the maximum between-class variance method further increases accuracy by 2.7%.

Smart retail has been increasing in interest due to societal shifts along with technological advancements. The fast-paced integration of artificial intelligence (AI) brings the opportunity to develop potential technology in the scope of daily activities. Smart retail implements a field of artificial intelligence that involves computervision to detect and recognize products. This paper aims to analyze the performance of YOLOv8 for brand recognition on grocery products. However, the inter-class similarities problems are present among certain grocery products included in the dataset to further represent real-life conditions of smart retail. Firstly, an adequate dataset is internally developed with common grocery products from 20 classes that represent brands. In the dataset developed, 3095 images were used and split into training, validation, and testing in 70%, 20%, and 10%, respectively. Then, an experiment is conducted with the YOLOv8 model where the performance result showed by precision, recall, mean average precision (mAP), and confusion matrix. Results of the experiment show that the YOLOv8 model gives a mAP50 value of 0.96303. This result indicates that the YOLOv8 model's performance for object recognition opened new insights into its potential in supporting the automatic checkout process in smart retail.

Glaucoma, a prevalent eye ailment, necessitates early detection and treatment to prevent irreversible vision loss. Conventional screening methods are often time-intensive and require specialized expertise, limiting accessibility, especially in remote areas lacking ophthalmologists. This study introduces a CNN model, harnessing deep learning to analyze retinal images and extract glaucomatous indicators. Evaluation of the CNN’s performance on a diverse dataset includes accuracy, sensitivity, specificity, and F-score assessment. Results underscore the CNN’s promise as an efficient and dependable tool for automated glaucoma screening. This advancement offers optimism for enhancing early diagnosis and intervention, critical for managing this sight-threatening condition.
