WebDemonstration of image registration using optical flow. By definition, the optical flow is the vector field (u, v) verifying image1 (x+u, y+v) = image0 (x, y), where (image0, image1) is a couple of consecutive 2D frames from a sequence. This vector field can then be used for registration by image warping. To display registration results, an RGB ... WebJul 15, 2024 · opticFlow = opticalFlowHS; for i=1:2 frameRGB = frame {i}; frameGray = im2gray (frameRGB); flow = estimateFlow (opticFlow,frameGray); imshow (frameRGB) hold on plot (flow,'DecimationFactor', [5 5],'ScaleFactor',60,'Parent',hPlot); hold off pause (1) end The flow variable stores the optical flow between the two images (frame1 and frame2). WebA novel ego-motion estimation algorithm for hovering robots equipped with inertial and optic-flow sensors that runs in real-time on a microcontroller and enables autonomous flight and does not rely on feature tracking, structure estimation, additional distance sensors or assumptions about the environment.
