WebThe rolling-ball algorithm estimates the background intensity of a grayscale image in case of uneven exposure. It is frequently used in biomedical image processing and was first proposed by Stanley R. Sternberg in 1983 [ 1]. The algorithm works as a filter and is quite intuitive. We think of the image as a surface that has unit-sized blocks ... http://duoduokou.com/algorithm/27492138519799511088.html
OpenCV: cv::BackgroundSubtractorMOG2 Class Reference
WebBasically, background subtraction technique performs really well for cases where we have to detect moving objects in a static scene. As the name indicates, this algorithm works by detecting the background and subtracting it from the current frame to obtain the foreground, that is, moving objects. In order to detect moving objects, we need to ... We discuss the main parts of the code above: 1. A cv::BackgroundSubtractorobject will be used to generate the foreground mask. In this example, default parameters are used, but it is also possible to declare specific parameters in the create function. 1. A cv::VideoCaptureobject is used to read the input video or input … Ver mais In this tutorial you will learn how to: 1. Read data from videos or image sequences by using cv::VideoCapture; 2.
