Edges are detected by finding the lines that maximize the gain function, which measures the dissimilarity between regions on opposite sides of the postulated line. To cope with the wide range of images, the method has to be topological, avoiding a high sensitivity to the exact pixel values. ...
When there is an edge (i.e. a line), the pixel intensity changes rapidly (i.e. from 0 to 255) which we want to detect. But before doing so, we should make the edges smoother. As you can see, the above images have many rough edges which causes many noisy edges to be detected. ...
The combined mask filters the yellow and white lines very clearly. Canny Edge Detection The Canny edge detector was developed by John F. Canny in 1986. We want to detect edges in order to find straight lines especially lane lines. For this, use cv2.cvtColor to convert images into gray scal...
Finding straight lines in the image space is therefore equivalent to finding intersection points in the Hough space. In practice, the measured points do not lie exactly on a straight line, and the lines in the Hough space do not intersect exactly in a single point. The usual approach is to...

Animals have evolved mechanisms to travel safely and efficiently within different habitats. On a journey in dense terrains animals avoid collisions and cross narrow passages while controlling an overall course. Multiple hypotheses target how animals solv
This example of a complex network comprises 16 nodes and 21 edges. Set nodes 2 and 5 as central nodes and observe the alterations in the paths of information dissemination among their neighbors by removing them. Full size image Due to the removal of a node will influence the dissemination of...
then run the VBA for the accurate list of IDs, and by that time the formulas already found that Jane Doe who moved from the US to the UK, so by her ID, in the country column the UK is displayed and there is a YES in the change column so we can filter to only see th...
