[Special Effects] ALC_Ray_Caster DL : 0: 本文介绍的剪切图像顺序光线投射，一个新的体绘制方法。这种方法使得采样数据在图像质量相当于三个尺寸，最好的射线每像素体绘制算法（全图顺序），而在同一时间计算复杂度和保留空间相干性接近已知的最快算法（剪切变形）。在剪切图片的顺序，如剪切，弯曲，体积数据集重新取样片沿平行于其他物体的射线。不同剪切变形，但象纹理为基础的方法，射线演员通过对图像的像素的平面和样品中心点是在与每个切片射线的交点。-This paper describes shear-image order ray casting, a new method for volume rendering. This method renders sampled data in three dimensions with image quality equivalent to the best ofray-per-pixel volume rendering algorithms (full image order), while at the same time retaining computational complexity and spatial coherence near to that of the fastest known algorithm (shear-warp). In shear-image order, as in shear-warp, the volume data set is resampled along slices parallel to a face of the volume. Unlike shear-warp, but liketexture-based methods, rays are cast through the centers of pixels of the image plane and sample points are at the intersections of rays with each slice.

[Special Effects] Homography Estimation Techniques DL : 0: The estimation of the homography between two views is a key step in many applications involving multiple view geometry. The homography exists between two views between projections of points on a 3D plane. A homography exists also between projections of all points if the cameras have purely rotational motion. A number of algorithms have been proposed for the estimation of the homography relation between two images of a planar scene. They use features or primitives ranging from simple points to a complex ones like non-parametric curves. Different algorithms make different assumptions on the imaging setup and what is known about them. This article surveys several homography estimation techniques from the literature. The essential theory behind each method is presented briefly and compared with the others. Experiments aimed at providing a representative analysis and comparison of the methods discussed are also presented in the paper

[Special Effects] 指纹识别源代码 DL : 0: To match a Fingerprint image with a one already stored in the database. A fingerprint image essentially consists of a set of minutiae on the plane. Minutiae are the terminations and bifurcations of ridge lines in a fingerprint image. A new approach towards fingerprint recognition is to match the distribution and orientation of such points.
