The total variation-based Rudin–Osher–Fatemi model is an effective and popular prior in the image processing problem. Different to frequently using splitting scheme directly solve this model, we propose primal dual method smoothing give some convergence analysis of proposed method. Numerical implements show that our can efficiently improve numerical results compared with model.
Enabling multi-fingered robots to grasp and manipulate objects with human-like dexterity is especially challenging during the dynamic, continuous hand-object interactions. Closed-loop feedback control essential for dexterous hands dynamically finetune hand poses when performing precise functional grasps. This work proposes an adaptive motion planning method based on deep reinforcement learning adjust grasping according real-time from joint torques pre-grasp goal grasp. We find multi-joint of...
The beam hardening effect can induce strong artifacts in CT images, which result severely deteriorated image quality with incorrect intensities (CT numbers). This paper develops an effective and efficient correction algorithm incorporated a filtered back-projection based maximum posteriori (BHC-FMAP). In the proposed algorithm, is modeled into forward-projection of MAP to suppress induced artifacts, update process performed by Feldkamp-Davis-Kress method speed up convergence. BHC-FMAP...
During any image segmentation process, two distinct tasks are performed - <i>recognition</i> and <i>delineation</i>. Recognition consists of the searching phase which roughly identifies a particular object interest among other neighboring structures present in image. Delineation precisely defining spatial extent region. Well designed interactive methods, such as live wire (LW) snakes, exploit synergy between user knowledge (for recognition) underlying computer processing done automatically...
Differential phase-contrast computed tomography (DPC-CT) is a novel x-ray inspection method. Currently, DPC-CT reconstruction problems are solved by using parallel-beam, fan-beam and cone-beam algorithms. The above algorithms cannot show the internal structures of rod-shaped objects well enough for only reconstructing few slices. helical have significant advantages over other Along with our numerical evaluation verification, we report PI-line-based approximate algorithm DPC-CT, which can be...
The authors present a camera calibration method for estimating the extrinsic parameters and focal length of using only single image planar rotation‐symmetric pattern. frontal parallel pattern can preserve pattern, causing corresponding frieze‐expansion (FE) to be expressed as low‐rank matrix, which does not exist when is captured from an oblique view. proposed derives forward formulation between FE observed view low‐rank, image. An optimisation problem arises rank minimisation techniques are...
In order to improve the corrosion resistance of CoPtP film in 3.5% NaCl solution, effects deposition current, temperature and perpendicular magnetic field (PMF) preparation process were investigated. Results indicated that solution was controlled by cathodic process. At condition current 0.08 A, 60 C PMF intensity 0.5 T, deposited displayed good lowest density 1.995×10-6 A/cm2 The increase beneficial refine grains enrich CoPx substances film. However, higher resulted uneven stress severer...
Image inpainting is an active research area in the image processing field. The essential idea of algorithm to fill missing or damaged regions with available information from their surroundings. In this paper, we propose two models based on variational method. We show that diffusion performance proposed for are superior classical total variation (TV) model according physical characteristics local coordinates. To effective models, apply it restoring scratched photos, text removal and even...
Because of the complex operation and poor relevance to special use, current general GIS software cannot usually meet need setting up a GIS. The ESRI product ArcGIS provides set COM components, called ArcObjects. Based on ArcObjects, can be conveniently. To develop management information system for Fuzhou's active faults, we use Visual Basic as our developing tool, which call making good existing VBA codes. In this system, basic data professional are integrated display, query, analysis. With...
