revanalyzer.vectorizers.persistence_image_vectorizer

Definition of Persistence Image vectorizer, used in PD vectorization. A persistence image is a 2D function computed from a persistence diagram by convolving the diagram points with a weighted Gaussian kernel. The plane is then discretized into an image with pixels, which is flattened and returned as a vector. See Adams H. et al., (2017).
