[Speech/Voice recognition/combine] 16to8K-Downsample

Description: 本程序将指定的16K采样的语音数据文件转换为经G.723编解码后的8K语音数据。降采样前先使用180阶的FIR滤波器对语音数据进行频率压缩，然后进行抽取，并对抽取的数据进行G.723编解码。该程序在非特定语音识别的库文件处理中使用，也可扩展至其他用途。-this procedure will be designated the 16K sampling voice data files converted to G.723 codecs by the 8K words Music data. Sampling down before use 180 bands FIR filter frequency voice data compression, then proceed to collect, also collected data G.723 codecs. The procedures in non-specific voice recognition for the use of document processing, and can be expanded to other uses.

[VC/MFC] FroggyAA

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.

[Special Effects] Segmentation

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.

[SCM] Question2

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 templates.
