Description: This sample shows different ways of performing anti-aliasing - both by using only
the native hardware AA support, and by mixing the hardware modes with additional
supersampling. There are various ways in which the supersampled image can be
down-sampled. The way we do the downsampling in this example is the same
technique that was used in 2 of our latest launch demos – “Froggy” and “Adrianne”.-This sample shows different ways of performing anti-aliasing- both by using onlythe native hardware AA support, and by mixing the hardware modes with additionalsupersampling.

Description: 这个方法有两个好处。
（ a ）虽然只是一个半径差逼近，很容易找到最高在一个小蓄电池，因为通过降低 隐平滑做的蓄电池。（ b ）在同一时间处理时间搜索减少
-Pattern Recognition and Image Procesing Group.
The size of the accumulator is varied as hierarchical voting is performed. This
has two advantages.
[a] While the radius is only a poor approximation, it is easier to find the maximum
in a small accumulator and because by means of the downsampling
implicit smoothing is done to the accumulator.
[b] At the same time processing time for the search is reduced. Platform: |

Description: Images passed to your application are not always of the same size as your
templates. To compare them you might need to up scale or down scale them to
the template size. It is preferred that when comparing you check the size of the
template to be compared then adjust the size of the incoming image to be
compared. For simplicity you can do it for the following sample only.
Hints:
• Upsampling by interpolation/replacement
• Downsampling by interpolation/replacement
• Refer to sample code given in first tutorial for ways to create
images of similar width and height.-Images passed to your application are not always of the same size as your

Description: 该代码实现了以2为因子的图像升采样和降采样功能。
降采样包括使用平滑滤波器(with using the averaging filter)和不使用平滑滤波器(without using the averaging filter)两种方法。
升采样包括像素点直接复制(pixel replication method)和线性插值(bilinear interpolatoin method)两种方法。
降采样方法和升采样方法共有4种组合。程序运行后，给出了一个原始图片和四个结果图片。

Description: 打开一副BMP图片，读取BMP文件中的数据，获取图片中像数点RGB的数值，显示到屏幕界面中。（如果不能打开BMP可以先试着打开YUV文件，然后计算第二步的内容）
将RBG数据转换成YUV格式的，并计算Y分量的平均值，统计出图像灰度直方图，显示直方图。
将RGB数据表述的图像进行2：1的下采样，原来图像是2Xx2Y的宽高大小，新的图像为XxY的大小图像，并显示到界面中。-Open a BMP picture, read BMP file data, the number of points for pictures like the RGB values to the screen interface. (If you can not open BMP can first try to open YUV file, and then calculate the contents of the second step) to RBG data into YUV format, and calculate the average value of the Y component, the statistics of the image histogram, histogram display. Expressed in the RGB image data is 2:1 downsampling, the original image is a 2Xx2Y size width and height of the new size of the image is XxY images and displayed on the interface. Platform: |
