WebOur approach is based on a technique for the numerical solution of eigenfunction problems known as the Nyström method. This method allows one to extrapolate the complete grouping solution using only a small number of samples. In doing so, we leverage the fact that there are far fewer coherent groups in a scene than pixels. WebFeb 13, 2024 · Spectral clustering for image segmentation is a graph theory-based information extraction procedure which describes the image as a weighted graph and partitions them using optimized cost function.
