How to distort an image in OpenCV?

OpenCV doesn't provide distort function for image, but you can implement one by yourself. All you need are: Intrinsic params (camera matrix and distortion coefficients) and size of the distorted image. Denoted as cam_mtx, dis_cef, and image_size. Intrinsic params (camera matrix) and size of the undistorted image.

How to use blob detection in OpenCV?

How many distortion parameters are there in OpenCV?

So we have five distortion parameters which in OpenCV are presented as one row matrix with 5 columns: Now for the unit conversion we use the following formula: Here the presence of is explained by the use of homography coordinate system (and ).

How to find dense optical flow in OpenCV?

Lucas-Kanade method computes optical flow for a sparse feature set (in our example, corners detected using Shi-Tomasi algorithm). OpenCV.js provides another algorithm to find the dense optical flow. It computes the optical flow for all the points in the frame.
