We introduce a novel coarse ridge orientation smoothing algorithm based on orthogonal polynomials, which can be used to estimate the orientation field (OF) for fingerprint areas of no ridge information. This method does not need any base information of

日本独立行政法人"情报通信研究机构"(NICT)以吉田俊介为首的研究团队日前表示,他们已经成功研发全球首台无需特殊眼镜的3D立体影像投射装置。虽然立体影像的精致度仍有待提升,但科幻电影中悬浮于眼前的立体影像绝非痴人说梦。日后我们很可能坐在自家客厅中,就能体验亲临现场的逼真视觉感受。据日本"产经新闻"报导,吉田的研究团队在直径约80公分的桌子底下,设置圆锥形显示器,辅以排列成圆形的96台投影机,以及
三维角色动画是一门新兴技术产业。它不仅与美术、设计方法有关,同时它与软件技术及软件方法是密切相关的。角色装配工作是三维动画制作中实现角色动画制作的关键步骤,优秀的装配系统可以帮助动画师高质高效地完成角色动画制作,在此基础上还需要通过行为规划和路径规划,以及个体运动模型和物理模型,才能控制角色产生反应动作行为。
提出了一种基于DCT变换的局部化数字图像水印算法,该算法利用基于Hausdorff测度的分类器,将水印信息嵌入到具有复杂纹理结构的图像块中,从而提高含水印图像抵抗切割攻击的鲁棒性,同时采用相关检测算法提高水印检测和提取的准确性。实验结果表明,所提出的算法具有良好的不可见性、低虚警率和安全性,在抵抗通常的噪声、频率域滤波、JPEG压缩、图像增强以及图像切割方面具有鲁棒性。
In this paper,we present a novel approach to synthesizing frontal and semi-frontal cartoon-like facial caricatures from an image.The caricature is generated by warping the input face from the original
基于弹性网格方法能够在一定程度上吸收手写汉字形变因而在汉字识别中取得较理想的效果,在传统弹性网格的基础上,提出一种新的伪二维弹性网格,通过对手写汉字图像的局部线密度进行模糊化与均衡,得到非四方形的曲线网格,相比由全局密度投影均衡生成的传统弹性网格有更好的吸收局部形变的能力.将多种特征提取方法与伪二维动态网格结合进行实验,与结合传统弹性网格比较,取得更为理想的识别率.由于避免了非线性归一化方法产生的
In this paper, we investigate how to extract the lowest frequency features from an image. A novel Laplacian smoothing transform (LST) is proposed to transform an image into a sequence, by which low fr
To overcome the problem of multi-sensor image fusion,a technique for image fusion based on non-subsampled contourlet transform(NSCT) domain improved nonnegative matrix factorization(NMF) is presented.
Model resizing is a useful technique for model reuse. Non-homogeneous model resizing introduced by Kraevoy et al. is able to preserve important geometric features during anisotropic scaling. However,
A large number of applications in image processing and computer vision depend on image quality. In this paper, combining the forward diffusion with the backward diffusion by different weights, we pres
For ground target tracking with road constraints,the existing methods ignore the road width,which can lead to significant biases of the target state estimates when the road width is large.In this pape
