Computing the distance between objects is very similar to computing the size of objects in an image — it all starts with the reference object. Step 4 : Forward Pass. Jython is an implementation of the Python programming language designed to run on the Java platform. While image classification and tasks that involve some level of computer vision might require a good bit of code and a solid understanding, reading text from a somewhat well-formatted image turns out to be a one-liner in Python —and can be applied to so many real-life problems. Image Source: DarkNet github repo If you have been keeping up with the advancements in the area of object detection, you might have got used to hearing this word 'YOLO'.
