In this work, we propose an arbitrary-shaped text detection method, namely TextRay, which conducts top-down contour-based geometric modeling and geometric parameter learning within a single-shot anchor-free framework. The geometric modeling is carried out under polar system with a bidirectional ...
由于鱼眼镜头具有较大的LFOV(视野),如今不论在VR、AR还是自动驾驶领域都应用广泛。但是针对鱼眼镜头的目标检测算法研究还十分匮乏,主要是由于鱼眼相机固有的几何变换导致未知的空间失真和物体外观的大变化 现有研究★ 现有的针对鱼眼镜头的目标检测算法主要有两个角度。 Distortion correction-based 可以简单的理解这类方法...
The first step is to extract corner candidates using MPT based on the integral properties of the local contours in both the horizontal and vertical directions. Then, an approximation of the parabolic fit is calculated to localize the candidate corner points. The proposed method presents fewer false...

论文标题:SharpContour: A Contour-based Boundary Refinement Approach for Efficient and Accurate Instance Segmentation 论文地址:https://arxiv.org/pdf/2203.13312.pdf 论文代码:None image-20220609195438136 摘要 引入主题:实例分割性能已经达到较高水平,但边界区域的质量仍然不令人满意,这导致边界细化受到越来越多的...
There are a small but growing number of land-based examples of fossil contourites, based on careful analysis using the recommended three-stage approach to interpretation. Debate still surrounds the recognition and interpretation of bottom current reworked turbidites. 展开 ...
Each elementρlkis a tensor representation encapsulating the local structure at a point based on its neighborhood, obtained from the outer product of the gradient vectors oriented along thekthandlthdirections and weighted by the smoothing function. ...

interpolation has worse effect in real-time matching,and the method of extending to find closed point can get needed contour quickly.Besides,the paper gives the generation and application of geomagnetic contour layer for the geomagnetic navigation system based on electronic chart display information ...
projecting a dose cloud to overlap the three-dimensional model of the tissue surface based upon the treatment plan;confirming the dose cloud covers the area of tissue of interest; andapplying a dose of radiation sufficient to ablate the area of tissue of interest so as to inhibit selected ...
