Notch filtering for Electromyography signal to remove 60 Hz noise

GPU Accelerating Speeded-Up Robust Features. Many computer vision tasks require interest point detection and descr iption, such as real-time visual navigation. We present a GPU implementation of the recently proposed Speeded-Up Robust Feature extract

PX4 光流模块源码，第一次发布版，可能存在问题。这是现在最好的开源光流模块了。-PX4Flow is an optical flow smart camera. It has a native resolution of 752×480 pixels and calculates optical flow on a 4x binned and cropped area at 250 Hz (bright, outdoors), giving it a very high light sensi
