素图

When real-world images are captured in bitmaps, the image is divided into a grid and the pixel is the sampling unit.

当用位图描述真实世界中的图象的时候，----，像素是最小的单位。

Subpixel disparity is calculated by fitting a second-degree curve to the SSSD values. By intensity tracking of the image sequence and left right consistant check, wrong regions are removed in the disparity map and anisotropy diffusion filtering is introduced to smooth disparity map while preserving depth discontinuity.

采用曲线拟合的方法求解亚像素视差，通过左右一致性检验和图像序列的灰度跟踪，去除了视差图中的错误区域，并引入了各向异性扩散滤波对视差图进行保留深度突变的平滑处理。

In global mode, annular omnidirectional images are captured by using skip subsampling mode to guarantee high frame rate, and then unwrapped to cylindrical panoramic images containing global scene information of 360 degrees. In local mode, the location and size of sampling window of image sensor are reconfigured according to the position of interested region, thereby only a corresponding rectangle region of omnidirectional images is captured by using pixel-by-pixel mode, and then unwrapped to a high- definition local perspective image of the corresponding view angle. Finally, a hardware design based on DSP+FPGA is presented.

在全局模式下，为保证采集帧速率，使用行列跳跃模式采集完整的环状全向图，并将其展开为包含360°全局信息的柱面全景图像；在局部模式下，根据感兴趣区域的空间位置设置采样窗口大小及位置，以逐像素采样模式只采集全向图中相应的一块矩形区域，并将其展开为对应视线方向上高清晰度的局部透视图；最后给出了DSP+FPGA结构的系统硬件设计方案。

The file format of Bitmap is rectangular,while there are lots of applications of non-rectangle texture mapping.

位图文件格式决定了位图只能存储矩形区域的像素信息，而在实际应用中存在着大量的非矩形区域的纹理映射问题。

For instance, a bitmap representation of an entire 640-by-480-pixel, 16-color Video Graphics Array screen requires more than 150 KB; a 1024-by-768 image with 24 bits per pixel requires more than 2 MB. Metafiles usually require much less storage space than bitmaps.

对于位图而言它占用空间的大小取决于图象的大小和颜色数量（也就是分辨率和像素位数4S）。

The main target of MRI brain image segmentation is to delineate profiles of neuroanatomical structures and also label each voxel as belonging to a specific structure.

MRI颅脑图象分割的目的是勾勒出脑组织解剖结构的轮廓，并将脑图中各体素标记为所属的组织。

METHODS According to In-ternational Society for Clinical Visual Electrophysiology's standard program,we recorded the scotopic electroretino-graph,oscillatory potentials,photopic electroretinographand30Hz flicker response in diabetic rats for2weeks,by using REPIport system,Ag-AgCl corneal contact electrode and stainless steel needle elec┐trode.

按照国际临床视觉电生理学会的标准化方案，采用REPIport系统和银-氯化银角膜电极以及不锈钢针状电极对链脲霉素诱导的糖尿病大鼠模型进行2wk的暗适应视网膜电图、振荡电位、明适应视网膜电图和30Hz闪烁反应记录（30Hz flicker）。

Secondly,how to utilize the grid pheromone system model to realize the algorithm based on ACS is explicated. This refers to the construction of TRAG by the random selection of appropriate resources for each task by the user agent and the optimization of TRAG through the positive feedback and distributed parallel computing mechanism of the ACS.

其次说明了基于蚁群系统如何利用网格信息素系统模型实现该算法，涉及任务资源分配图的构造，以及通过蚁群的正反馈和分布式并行计算机制优化任务资源分配图。

The algorithm first divides the scene into certain layers that do not intersect each other by light's frustums in light space, and generates one shadow map for each layer to ensure that any shadow map does not have the same sample points. Then a faster synthesizing scene shadow method, which avoids operations of pixel layer determination, is given to improve GPU's efficiency.

在光源空间中，利用光源视锥体将场景划分为不相交的多层区域，利用GPU为各层生成阴影图，以确保场景采样点不在多层阴影图中重复出现；同时给出了一种快速综合场景阴影效果的绘制方法，通过避免判断像素层次的操作提高了GPU的利用率。

The main technique applied in our method is derived from the features of the eight bit-planes of a gray image. The XOR bit-wise operation is used for two bit pixels among the neighboring bit-planes from the most significant bit to the least significant bit.

本提出方法是将欲隐藏之灰阶影像分解成八张位元平面，并利用其影像前几个位元平面0与1分布会有群聚现象，将两两位元平面间作XOR (Exclusive-or)运算，再使用线性四元树的观念将运算后的资料进行有效BFS编码，之后再隐藏於伪装图之像素最低位元，使最后藏入资料的伪装图影像仍呈现高度清晰的图像显示，也就是说PSNR的测度皆能远大於30dB。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
