In computer vision, the gradient and Laplacian of an image are used in different applications, such as edge detection, feature extraction, and seamless image cloning. Computing the gradient of an image is straightforward since numerical derivatives a

In Computer Vision, edge detection is one of the favored approaches for feature and object detection in images since it provides information about their objects boundaries. Other region-based approaches use probabilistic analysis such as clustering a

In this thesis, we will work with the nodal sets of Laplace eigenfunctions on a few simple manifolds, like the sphere and the flat torus. We will obtain bounds on the total Betti number of the nodal set that depend on the corresponding eigenvalue. Ou
