I really don't know what to do. We have to write a OpenCV program with using Java. And we have to load and storage an image in the Mat-Class from OpenCV. I never worked with OpenCV. And additional I am not really the best in programming Java. So I really don't know how to start and what to do next :(

I only think that I need to use the Highgui imread and imwrite. But dont know how to write it down :(

Pls could anybody here send me a example code with loading and storage images in Mat-Class from OpenCV using Java?

It would be such a big help for me.

Hi, our task is: Given one colored image of the KITTI dataset load it and store it in the Open CV "Mat" class. How can you extract the value of one pixel? Find the corresponding method and interpret its output. Split the image into its 3 R,G,B channels plotting them. How do they look like with respect to the original image? Are these images colored or in greyscale? What are the di erences among them? Why? How can you remove one channel from the original image?
