Firstlly, architectonic analysis about information hiding detection is proposed, including the analysis of digital image characteristics, image based detecting algorithms and some problems in its realization.

静止图像是像素的集合，相邻像素点所对应的实际距离称为图像的空间分辨率。根据像素颜色信息的不同，数字图像可分为二值图像，灰度图像以及彩色图像。

If your pixel scale is much larger than the values quoted above, then the quality of the astrometry will suffer. If your pixel scale is too low for your local setup, then the signal-to-noise of the images may be low as each image is spread over a large number of pixels.

如果你的像素分辨率比上面要求大很多的话，那么可能导致天文测量的测量品质下降，但如果你的像素分辨率比上面要求的小很多，则会导致图片的信噪比下降，因为每个目标占据了过多的像素。

The grey scale of the pixels in image is expressed by quantum bit and the relation between two pixels is described by means of the superposition of two quantum bit in this paper.Based on this,the average of linear hermitian operator in this superposition can be used for judging the edge of image and a new method for edge detection of image is so created.The rationality of the method is interpreted by probability theory here.

利用量子比特表示图像像素的灰度，用双量子位叠加态来描述两像素之间的关联，通过线性厄米算符在该量子叠加态中的平均值来判断像素的边缘特征，由此建立了一种新的图像边缘检测方法，并从概率论的角度对该方法的合理性给予解释。

In this paper, an increasing sequence of structure element was used to detect the best response to each pixel of image and the output of the response pixel would be the most sensitive structure element by using this improved Top-Hat transform.

通过定义一个递增的结构元素序列对图像进行Top-Hat变换，在每一个像素处用不同的结构元素作Top-Hat变换，以寻找对该像素最敏感的结构元素，并把此结构元素对图像的处理结果作为该像素处最后的输出值。

The edge pixel is processed by Partial Differential Equation. PDE enhances edge and smoothes jaggies in the edge. The pixel in smooth regions of under-interpolated image is processed by Non Local-means model. NL-means model gets gray value of pixel by weighted averaging global information in image and image is smoothed.

使用偏微分方程处理边缘像素，锐化边缘同时平滑边缘块状效应；平滑区域像素点的插值操作使用非局部均值模型，非局部均值模型通过对原始图像全局信息加权平均得到待处理图像像素值，图像平滑。

The invention intercepts a pixel area with the scheduled size in each frame from several continuous frame images in turn, reduces the intercepted pixel area to the largest size which the scheduled storage space can store and is stored in the scheduled storage space, then detects the face in the stored pixel area, hence, due to the minification of the storage space pixel area having the same size smaller than the whole frame image, thereby increasing the pixel area and reducing and storing the object face size compared with the whole frame stored in the storage space after reducing the frame image.

本发明依次从连续几帧图像中的每一帧中截取预设大小的像素区域，并在每次截取后，均将截取的像素区域缩小至预设存储空间所能够存储的最大尺寸后存储在预设存储空间内，然后在存储的像素区域内检测目标人脸。

FG is an interpolated technique. This means that the indirect lighting is sub-sampled (calculated less than for every pixel) and the values between those are interpolated. However, if you are doing an animation, and the result between two frames are slightly different, this may – hypothetically – cause not one pixel to change, but a large area of pixels to change (i.e. all pixels influenced by the interpolation of that FG point).

FG是一个以内差值替换计算的技术，这意味着非直线的漫反射光线被二次采样，（根据其少于每个像素的值计算），然后从中选出基于两个数中间的值被选为插值，然而，如果你是在制作一部动画，那么前后两帧之间的结果是明显不同的，这可能——假设——不仅仅导致一个像素的改变，而是一整块区域像素的改变（也就是说，所有的像素都受那个FG采样点的插值的影响）。

Firstly, edge extracting is conducted with a laplace operator for a k frame image of fk and a k-1 frame image of fk-1 collected by a camera; secondly, difference calculus is conducted for images of two frames whose edge is extracted, and a difference image of D is obtained; thirdly, average filtering and binary processing is conducted for the difference image of D, fourthly, the image which is processed of binary is judged, i.e. when the difference of a pixel in the difference image is more than the set threshold value, the pixel is confirmed as a target pixel; otherwise, the pixel is a static background pixel.

首先对摄像头采集的第k帧图像f k和第k-1帧图像f k-1分别采用laplace算子进行边缘提取，然后对经过边缘提取的两帧图像进行差分运算，得到差分图像D，然后对差分图像D进行均值滤波和二值化处理，最后对二值化后的图象进行判断，即认为当差分图像中某一个像素的差大于设定的阈值时，则认为该像素是目标像素，反之则认为是静止不动的背景像素。

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
