图像

From the exterior visual angle, the cultivation of visual literacy depends on social education and the public self-education, but from the interior visual angle, the visual literacy deals with the psychology of visual cognition, especially the Gestalt psychology.

从外部看，图像文本的识读、图像素养的培养，取决于社会教育和公众的自我教育；而从个体内部看，它与公众的图像认知心理密切相关。

It is a technology that carries on the spatial matching to a series of image which are overlapped partly with each other, and finally generates a seamless and big eyespot image by merging these images.

它首先对一组相互之间存在部分重叠的图像进行配准，然后再融合成为一幅包含整组图像信息的大视场图像。

Example3:Exposure control:film speed Exposure: on, Shutter Speed (s^-1): 60.0, f-number: 8.0, Vignetting: on, White balance: white

这项参数决定了图像对光的灵敏性-感光度。如果胶片速度值较高那么图像将会对光线更为敏感，图像也就越亮。

At present, most of the image watermarking algorithms based on the wavelet transform fail to take into account the shortcoming that the first generation wavelet transform used in image processing will introduce quantization errors inevitably, because of the storing characteristics of the image. Wavelet transform that maps integers to integers will not introduce quantization errors. Its time-frequency analysis method and multi-scale property accordant with human being vision system makes integer wavelet transform an ideal way for digital watermarking.

目前，大多数基于小波变换的图像水印算法没有考虑到第一代小波变换用于图像处理中不可避免的引入量化误差的缺点，而整数小波变换除了具有小波的多分辨率分析与人类视觉特性一致、具有良好的时频特性等优点以外，还避免了第一代小波变换用于图像处理中引入量化误差等缺点。

But the fisheye image taken this way possesses a kind of distortion at different level.

这样得到的图像被称为鱼眼图像。鱼眼图像都有不同程度的变形和失真。

Filter-based matching algorithm uses a bank of Gabor filters to capture both local and global details in a fingerprint as a compact fixed length Feature Vector. Invariant-moment matching algorithm is used to overcome the deformation in fingerprint.

用一组Gabor滤波器获取指纹图像的局部信息和全局信息，并表示成简洁的指纹滤波特征向量，用于滤波特征匹配；针对指纹图像中存在的三种形变，采用图像的不变矩算法进行不变矩的匹配。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。

In a polar coordinate system, the concept of image area extension is established, and the uniqueness problem is discussed for an image whose Fourier series expansion of grey only contains the 0th-order and 1th-order terms.

同时本文以极坐标系表示图像平面，建立了图像区域延拓的概念，讨论了由灰度关于极坐标系角度坐标的富里叶展开式仅含零阶和一阶项之图像恢复物体外形的唯一性问题。

The Image Acquisition Toolbox provides functions for acquiring images and video from PC-compatible frame grabber cards and video devices.

该图像采集工具箱提供职能获取图像和视频从PC兼容的图像采集卡和视频设备。

The scanned image of the fingerprint is converted into a grey scale image, similar to a black and white photo and converted to a binary image, by a 'frame grabber'.

指纹的被扫描的图像转换成一个灰色的刻度图像，相似的到一张黑白的相片而且转换到一个二进位的图像，被一'体格贪心者'。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
