Sewer pipes are currently manually inspected by trained inspectors, making the process prone to human errors, which can be potentially critical. There is therefore a great research and industry interest in automating the sewer inspection process. Previous research have been focused on working with 2D image data, similar to how inspections are currently conducted. There is, however, a clear potential for utilizing recent advances within 3D computervision for this task. In this paper we investigate the feasibility of applying two modern deep learning methods, DGCNN and PointNet, on a new publicly available sewer point cloud dataset. As point cloud data from real sewers is scarce, we investigate using synthetic data to bootstrap the training process. We investigate four data scenarios, and find that training on synthetic data and fine-tune on real data gives the best results, increasing the metrics by 6-10 percentage points for the best model.

Content-based image retrieval (CBIR) is a critical domain in computervision, dedicated to extracting images from databases based on their visual content rather than relying on text-based queries. Feature extraction plays a pivotal role in CBIR, converting image attributes like color, texture, and shape into numerical representations, facilitating efficient image matching. It lacks a comprehensive exploration of the distinct impacts of fusion methods and often falls short in detailing feature extraction architectures. This paper introduces a novel approach to tackle the proposing a hybrid feature extraction method. The method evaluates its performance using the Corel 1K dataset, a collection of 1,000 images spanning diverse categories, serving as a benchmark for assessing the efficacy of content-based image retrieval techniques in real-world scenarios. The results achieved by the proposed hybrid feature extraction method surpass those of existing models, with impressive precision (0.956), recall (0.872), and F -measure (0.892). This method is compared to the KMFO model and performance evaluation in CBIR using the SVM model. Future research is focus on refining and optimizing advanced feature extraction techniques to enhance the efficiency and effectiveness of CBIR systems.

Fruits contain a lot of fiber. Fruits contain biologically active substances that improve our health. This study focuses on identifying and classifying guava fruit diseases. Guava disease has become a significant issue for guava production, threatening farmers’ socioeconomic growth. As a result of this phenomenon, an automated computervision-based guava disease diagnosis system was developed that can detect malicious guava and direct it to early cure approaches, reducing relative economic loss. In light of this, we present in this study a guava illness detection and categorization recommendation approach based on convolutional neural networks (CNN). This paper employs transfer learning to classify images using our customized convolutional neural network (CNN) model architecture. The photographs in the data set were obtained from the Mendeley Data website. The data set includes 306 images of healthy and unhealthy guava fruits and leaves. The four disease classes targeted by the data sets are dot, Canker, mummification, and Rust. We obtained an average accuracy of 74.72% for training and 34.74% for testing from the data set used.

Aiming at the problems such as low simulation accuracy, slow dynamic response and poor anti-interference ability of traditional control methods for linear or nonlinear loads, a three-vector model predictive current control method based on fast prediction sector judgment is proposed. Firstly, the mathematical model of α-β coordinate system is established, and the relationship between the expected voltage vector and the basic voltage vector is analyzed. Then using the sector decision condition proposed in this paper, the sector in which the desired voltage vector is located can be quickly determined. This method greatly reduces the amount of computation required to perform 6 times cost function evaluation in traditional three-vector control method. Finally, two-step prediction is introduced to compensate for sampling and calculation delay. The simulation and experimental results show that the proposed control method can shorten the adjustment time by 0.1s compared with the traditional PI control, effectively improve the simulation accuracy of nonlinear load, and reduce the calculation amount by about 70% compared with the traditional three-vector method.
