The YOLO series of target detection networks are widely used in transportation targets due to the advantages high accuracy and good real-time performance. However, it also has some limitations, such as poor scenes with large-scale variations, a large number computational resources being consumed, occupation more storage space. To address these issues, this study uses YOLOv8n model benchmark makes following four improvements: (1) embedding BiFormer attention mechanism Neck layer capture...
Source camera identification forensics aims at determining and authenticating the original sources of digital images to support get trace images. This paper introduces a new wavelet features based passive forensic method for image source camera. We consider intrinsic defects processing imaging pipeline within cameras can be used formulate problem. Based on this idea, we extract higher-order coefficient co-occurrence from taken images, then apply sequential forward feature selection (SFFS)...
Excessive pressure drop within the internal flow channel of water hydraulic throttle valve will generate severe noise. In order to reduce noise valve, in this paper, model was established, and characteristics acoustic were simulated. The simulation results showed that parameters throat structure, such as half angle, inlet angle length, have a significant effect on valve. Then, three main structural used optimization variables, radial basis function (RBF) neural networks multi-island genetic...
Sensor pattern noise (SPN) has been proved to be an inherent fingerprint of a camera, and it broadly used in the fields image authentication camera source identification. However, SPN extracted using current denoising algorithm always contains content residual, which would significatively influence accuracy In this paper, novel patch-based (PB) sensor for identification is proposed solve problem. Low-complexity patches images are selected construct local reference SPN, least residual. The...
With the continuous development of automobile industry, fast and efficient body styling methods have become crucial. Although traditional hand-drawn sketches 3D modeling are feasible, they often consume lots time, manpower financial resources when faced with complex design requirements. Therefore, A quickly method for car modelling has a hot topic in field automotive design. This paper proposes three-dimensional wireframe model generation surface reconstruction based on single image any view...

The accurate detection of the pointer position is key automatic meter reading.Appropriate image preprocessing basis precise location scale zone and on dial.In this paper, images are preprocessed by grizzle, median filter binarization.In order to improve quality segmentation, an improved bigness method based gray stretch adopted in threshold segmentation.Experiments results show that effective thresholds obtained, useful information successfully reserved satisfactory segmentation achieved.
Car body design includes the construction of car sketches, 2D models and 3D models. The establishment high-quality usually relies on CAD software, which requires proficient operating skills, efficiency is relatively low compared with automatic modeling. If model engineer can not fully understand designer's time cost spent communication between two parties to be underestimated. How quickly automatically generate high quality parametric from sketches or images efficiently has become a...
With the explosive growth of Internet and dramatic increase in wireless access, there is a tremendous demand on multimedia delivery over networks. We give recent advances about video transmission discuss development.
