In summary, you are trying to find the equation of a line that is perpendicular to the gradient vector at a point and goes through the point. You first use the fact that the dot-product of two vectors is zero when they are parallel, and then use the equation of the tan...
Here's a visual of what the points might look like, where the intersection is the grid point and the walls are the vectors extending from the intersection, assuming each of the vectors have a length of 1 (excuse my terrible drawing skills). Since dot products flip when greater than 180 d...

From an image signal made up of a series of image signal components representing a radiation image, an abnormal pattern appearing as an approximately circular pattern in the radiation image is detected. A first finding device finds a prospective abnormal pattern appearing in the radiation image by ...
h . easy to write, and not really hard do compute either. a point lies on a line if the dot product between their vectors is zero. you probably don't need this, but it's useful to know. to turn homogeneous coordinates of a point back into "normal" coordinates, y...
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...
