Webb24 jan. 2024 · Slow feature analysis is a new method for learning invariant or slowly varying features from a vectorial input signal. It is based on a nonlinear expansion of the input signal and on the application of the principle component analysis (PCA) to this expanded signal and its time derivative. Webb’slow’ features are effective in human motion analysis and how we use SFA to extract these features from image se-quences (video). Then we elaborate the proposed DL-SFA algorithm for human action recognition. 3.1. Slow Feature Analysis One can treat perception as the problem of reconstruct-ing the external causes of the sensory input to ...
