先前我们已经研究了如何通过关键点和特征来描述对象,以及如何在同一物理对象的两个不同图像中找到对应点。 但是,在识别现实环境中的对象并将其分配给概念类别时,我们以前的方法相当有限。 例如,在第 2 章“使用 Kinect 深度传感器进行手势识别”,图像中所需的对象是手,必须将屏幕很好地放置在手掌的中央。 如果我们...

filter(ImageFilter.BLUR) image.save('code.jpg', 'jpeg') SimpleCV SimpleCV 是一个用于构建计算机视觉应用程序的开源框架。使用它,可以访问高性能的计算机视觉库,如 OpenCV,而不必首先了解位深度、文件格式、颜色空间、缓冲区管理、特征值或矩阵等术语。但其对于 Python3 的支持很差很差,在 Python3.7 中使用...
