The invention provides a video motion amplification method, and belongs to image processing methods. The problems that the noise is greatly increased by adding an amplification factor in the existing video motion amplification method based on linear Euler and that the video motion amplification method based on plural operational pyramids suffers motion distortion and the like are solved. The video motion amplification method comprises the steps of video image decomposition, video frame color space conversion, N-layer pyramid decomposition, time domain bandpass filter, second spatial frequency band group amplification, acquisition of a fourth spatial frequency band group, reconstruction of a brightness matrix, restoration of a video frame color space, and output of a video image and the like. By adoption of the video motion amplification method, the problems that the noise is greatly increased by adding an amplification factor in the existing video motion amplification method based on linear Euler and that the video motion amplification method based on plural operational pyramids suffers motion distortion and the like are solved, and the video motion amplification method is suitable for small space-time motion amplification.
Description
technical field [0001] The invention belongs to an image processing method, and in particular relates to a video motion amplification method, which is used for amplifying tiny spatiotemporal motion. Background technique [0002] The human eye has limited temporal and spatial sensitivity, and many real movements or color changes cannot be captured by the human eye, such as blood flowing through the skin, the skin color will change slightly, and the pulse caused by the periodic beating of the heart, however It is difficult for human eyes to observe the change of skin color and the beating of pulse. Using the method of video motion magnification, these motions that cannot cause visual responses can be amplified so that we can better observe various phenomena. [0003] Mallat and Meyer proposed wavelet multiresolution analysis (Multiresolution Analysis, MRA) in the late 1980s. Wavelet multiresolution analysis is based on the scaling and translation of wavelet functions and scal...
