| 2014-09-17 11:55:41 -0600 | asked a question | How is the edge detection in this video achieved? Here is the video in question: https://www.youtube.com/watch?v=CbwIJMz9PAQ#t=82 I've tried using Canny and Scharr edges to reproduce the effect, but the resulting live feed is very noisy, with hairs coming out of all the edges randomly. I've tried applying a Gaussian filter to the result, but the noise is no where near as low as is shown in the video. Any ideas? |
| 2014-08-06 15:21:06 -0600 | asked a question | Warp image to change perspective I am trying to figure out how to change an image such that something like this will become a top down view. The image is of a piece of paper, with five blocks that are all the same size. I would like the distorted image to contain just the piece of paper, and have the five blocks be roughly the same size. I am really new to OpenCV, and any help would be greatly appreciated! :) |
