As you probably already are aware of I have shown you earlier a vba macro I made that finds the shortest path between two points. There are obstacles between these two points to make it more difficult. The problem with that macro is that it could only show a path that moves up, down,...
A combinatorial algorithm to find a shortest triangular path (STP) between two points inside a digital object imposed on triangular grid is designed havingO(nglogng)time complexity,nbeing the number of pixels on the contour of the object andgbeing the grid size. First the inner triangular...
you can find the rotation matrix and R and translation vector t that maps the first set of points to the second one. It will also give you the angle of rotation in degrees, assuming we're talking about 2D. Once you have R and t, you need to solve for the point x that doesn'...

“two sets of double doors leading out of the antechamber, one marked STACKS and the other TOMES. Not knowing the difference between the two,” he tells Chronicler, “I headed to the ones labeled STACKS. That was what I wanted. Stacks of b...
Finding the optimal/best rotation and translation between two sets of corresponding 3D point data, so that they are aligned/registered, is a common problem I come across. An illustration of the problem is shown below for the simplest case of 3 corresponding points (the minimum required points ...
For example, gravity model-based multi-attribute fusion18 identifies the influential nodes by introducing the K-shell, degree, eigenvector centrality or distance between nodes into the gravity model, such as GSM19, MCGM20 and KSGC21. However, since the time complexity of these algorithms ...
How can i get the cosine similarity between these two documents? Thank you When indexing, there's an option to store term frequency vectors. During runtime, look up the term frequency vectors for both documents using IndexReader.getTermFreqVector(), and look up document frequency data for each...
