How to learn image processing / computer vision in a practical way? I am new to the field of image processing / computer vision and I find it very hard to get my hands on the subject.
I read a lot about the basics/theory but I feel in no way able to use this knowledge in a practical way.


Do you have any tips on how to translate my theoretical knowledge into practical knowledge?
Are there any "cookbooks" for image processing that are not bound to a software/library? (I plan to use Halcon but only find resources for Photoshop or OpenCV.)


Thanks in advance!
Digital Image Processing. Rafael C. Gonzalez, Richard E. Woods. - it is the classical book on Image Processing, that is not bound to any library.

To translate theoretical knowledge into practical knowledge you can start with the book Mastering OpenCV with Practical Computer Vision Projects, which can be downloaded here.
