纹理

A pixel shader performs per-pixel processing such as texture blending, lighting model computation, and per-pixel normal and/or environmental mapping.

PS 执行逐象素处理，比如纹理混合，光照模型计算，逐象素法向和环境映照计算。

Vertex Shaders even give you the possibility to decompress compressed position, normal, color, matrix and texture coordinate data and to save a lot of valuable band with without any additional cost .

顶点着色器一般会给你变性的压缩位置，法线，颜色，矩阵和纹理坐标数据及一些不带附加成本的有价值的带段。

Use the vertex normal, transformed to camera space, as input texture coordinates.

First, the proposed scheme uses contourlet transform to extract multidirectional and multiscale texture information, and then obtains the feature points invariant to the affine transformation from the low and middle directional subbands by Harris-Affine detector. Second, the feature regions are adaptively computed by the feature scale of the local structure and normalized by U transform. The watermarking is embedded adaptively in those characteristic regions which are normalized. Finally, by vector quantization, several copies of the watermark are embedded into the no overlapped local feature regions in different directional subbands.

首先，用Contourlet变换提取出多尺度、多方向的纹理信息；再用Harris-Affine检测算子从变换域的中、低频方向子带中提取出仿射不变特征点，结合自适应局部结构的特征尺度确定特征区域，并用U变换对其归一化处理，水印就自适应地嵌入到归一化后的区域中；水印嵌入采纳矢量量化的策略，将水印信息重复嵌入到不同方向子带、多个不相交的局部仿射不变特征区域。

Statistic analysis on IR image characteristics shows that IR target has relatively more and larger regions which are of same quality, mainly expressed by smooth images and by that the energy distribution is concentrated on low frequency band in L〓 linear normed space, while large quantity of background regions show as texture images and their energy in L〓 space is concentrated on high frequency band. Based on this difference, the IR target segmentation method on the basis wavelet transformation is proposed.

通过对红外图像特征的统计分析证明，红外目标含有较多较大的同质区，主要表现为平滑图像，在L〓线性赋范空间的能量分布集中在低频，而大量的背景区域表现为纹理图像，在L〓空间中能量集中在高频部分，根据这一差别，提出了一种基于小波变换的红外目标分割方法。
