In Taiwan's modern society, urban infrastructure plays a vital role, and the sewer system is the lifeblood of urban operations. However, due to the complexity and danger of the sewer environment, traditional cleaning methods have great risks and difficulties;manually entering the sewer to clean is not only dangerous, but may also cause labor health problems;the use of chemical cleaners also has environmental and health risks. This new system combines sweeping robots with image analysis and processing to significantly improve sewer cleaning efficiency while reducing risks. The machine has advanced sensing technology and photographic night vision capabilities to safely detect abnormalities and obstacles. Not only does it protect worker safety, it also helps protect the environment and reduces the use of chemical cleaners. This kind of technological innovation will bring about substantial changes in urban management, improve the maintenance efficiency of urban infrastructure, and ensure the stability and sustainability of urban operations.

In order to improve the detection and tracking speed of the objects on the video image,shorten the object tracking time,a method of machinevision technology based detection and tracking of the objects on the video image is proposed. The machinevision technology is analyzed and then introduced into the detection and tracking of the objects on the video image. The pixel difference operation is carried out between the video image and its front one to obtain a binary difference video image. The detection of the objects on the video image is completed by adjustment of threshold value. Finally,according to Camshift tracking algorithm flow, the color probability distribution map of the objects on the video image is obtained to complete the object tracking. Experimental results show that the tracking time of this method is significantly shortened compared with the traditional detection and tracking methods.

In recent years, due to UV human exposure, the number of skin cancers 'subjects' cases have been increased, therefore, the accurate detection of malign skin cancer at early stage is considered as very crucial for patients' therapy and to increase the survival rates. Melanomas is considered as the most frequent and dangerous type of skin cancer. Even a huge number of deep-learning (DL) and machine Learning (ML) based-classification methods have been introduced in the literature, there have been suspected cases during the clinical diagnosis of malignant lesions. This paper investigates and explores various DL-based models for an accurate diagnosis and detection of malign and benign skin lesions. Basically, Transfer learning (TL) techniques are adapted to efficient and accurate pre-trained models, mainly EfficientNet-B0-V2 and vision Transformers ViT-b16, on the image-Net datasets. Furthermore, a modified Convolutional Neural Network (CNN) model have been adopted and trained from scratch. A publicly available benchmark dataset has been used in order to evaluate the proposed models 'performances and to compare their effectiveness with state-of-the-arts exiting methods. The obtained results are respectively 79,70%, 86,52%, and 86.97% respectively for CNN, EfficientNet-B0-V2, and ViT-b16 models. The experiments have revealed the effectiveness of our proposed models compared to exiting DL and ML models for classification into benign and malignant skin lesions.

In recent years, semantic segmentation has become a pivotal tool in processing and interpreting satellite imagery. Yet, a prevalent limitation of supervised learning techniques remains the need for extensive manual annotations by experts. In this work, we explore the potential of generative image diffusion to address the scarcity of annotated data in earth observation tasks. The main idea is to learn the joint data manifold of images and labels, leveraging recent advancements in denoising diffusion probabilistic models. To the best of our knowledge, we are the first to generate both images and corresponding masks for satellite segmentation. We find that the obtained pairs not only display high quality in fine-scale features but also ensure a wide sampling diversity. Both aspects are crucial for earth observation data, where semantic classes can vary severely in scale and occurrence frequency. We employ the novel data instances for downstream segmentation, as a form of data augmentation. In our experiments, we provide comparisons to prior works based on discriminative diffusion models or GANs. We demonstrate that integrating generated samples yields significant quantitative improvements for satellite semantic segmentation - both compared to baselines and when training only on the original data.
