C# - Emgu cv How to load an image from a folder using CvInvoke.cvLoadImage("ClassPic1.jpg") as intptr and access it

Question

How to load an image from a specific folder using Emgu cv CvInvoke.cvLoadImage(...)?I am tryng to do it like this

    IntPtr inputImage = CvInvoke.cvLoadImage("C:\\Users\\...\\ClassPic1.jpg");

Is that ok? If so, How am i gonna access it later as an Emgu.CV.Image file so that i will do my image processing on it?

You should probably use the following method to load the image:

Image<Bgr, Byte> img1 = new Image<Bgr, Byte>("..\\..\\MyImage.jpg");// path can be absolute or relative.

this img1 variable can be accessed later to perform manipulations on it.

OpenCV functions are in CvInvoke class

so: CvInvoke.

those are all static functions.
