Witrynaangle (Image2)=angle (Image1) – vincet Nov 2, 2016 at 18:02 Add a comment 1 Answer Sorted by: 11 Yes, you are correct in that you need to manipulate the phase response. However, you are not swapping the phase response properly. To properly do what you are asking, you must also extract the magnitude of each image as well.

Witryna4 kwi 2016 · To get an image like the Farneback algorithm you must first understand what is the output. In OpenCV docs you have: prev (y,x) ~ next (y + flow (y,x) [1], x +flow (y,x) [0]) So, it is a matrix with the displacements between image 1 and 2. WitrynaCompute and plot a spectrogram of data in x. Data are split into NFFT length segments and the spectrum of each section is computed. The windowing function window is applied to each segment, and the amount of overlap of each segment is specified with …
