feature extraction

基本解释

Consider adding additional gesture recognition, such as pinch rotate through further feature extraction from the synclient output.
考虑添加其他手势识别，例如通过从 synclient 输出中进一步提取特征来识别按压旋转动作。
Next, the system might divide the image into blocks of 2 x 3 grayscale pixels, each block containing a single character; this is the feature extraction step shown above.
然后，系统可以将图像分成 2 x 3 灰阶像素的小块，每个小块包含一个字符；这是上图显示的特征提取步骤。
Instead of relying on feature extraction, Dr Tourassi's technique works by comparing the images taken by a radiologist with a large collection of normal and abnormal mammograms held in a database.
并不依赖于特征穷举法，Tourassi博士的技术，是把放射科医生拍下来的X光片放入，储存着大量正常与不正常图片的数据库中加以比较。
