OpenCV on a GPU Shalini Gupta, Shervin Emami, Frank Brill (3 years since v2. It seems like most modern devices will easily be able to handle the processing overhead associated with computer vision. Introduction Object Tracking is one of the key tasks in the field of computer vision. Instead of labeling the objects of interest in the video ourselves, we will let the algorithm decide which regions of a video frame are worth tracking. My goal is to track some circular objects of the same color (red) in a video. We chose to recognize the different hand shapes for rock paper scissors. Use features like bookmarks, note taking and highlighting while reading OpenCV: Computer Vision Projects with Python. detecting the different colors on the video framed is the keystone of contour based object tracking. There are 8 different trackers available in OpenCV 3. Object tracking is the process of locating an object or multiple objects over time using a camera. Given the real time webcam data, this paint-like python application uses OpenCV library to track an object-of-interest (a bottle cap in this case) and allows the user to draw by moving the object, which makes it both awesome and challenging to draw simple things. The tracked information can be send via OSC to other hard- and software. If you need a high-end GPU, you can use their. The MultiTracker is naive implementation of multiple object tracking.
