We consider the application of Koopman theory to nonlinear partial differential equations. We demonstrate that the observables chosen for constructing the Koopman operator are critical for enabling an ...

Abstract: This paper presents a video stabilization algorithm based on the extraction and tracking of scale invariant feature transform features through video frames. Implementation of SIFT operator ...

Create a function that changes the third element of an array given by the user. The function accepts a 1-D vector which has larger than three elements, then it makes the third element 0, and returns ...

Abstract: Image processing improve visual information to be useful in analysis in areas of medical imaging, satellite surveillance, and digital media. In this work, basic pre-processing functions, ...
