Even with all this, if an object is partially occluded, computers still won't recognize it. We may also share information with trusted third-party providers. Yes, we are not building it in a real way but it is all about graphics trickery. This is an unnecessary overhead, especially when we are working with many different projects. Run the following commands after substituting the right paths in the commands: It's time to install OpenCV 4.0.0. Consider the following screenshot: As you can see, we drew a green rectangle on top of the window. The imgcodecs module handles reading and writing of image files. This is very useful in developing interactive applications. The issue is that we still don't fully understand how our brain recognizes and organizes this visual data. To do this, we have to capture the same scene at multiple exposures, register those images with each other, and then blend them nicely to create this image. The reason we need to do this is because we will be using the OpenCV library in the form of dynamic link libraries (DLLs). Mastering OpenCV with Practical Computer Vision Projects is the perfect book for developers with just basic OpenCV skills who want to try practical computer vision projects, as well as the seasoned OpenCV experts who want to add more Computer Vision topics to their skill set or gain more experience with OpenCV’s new C++ interface before migrating from the C API to the C++ API.
