Since it starts with 0, the counting will be fine. The first line of the loop is the frame_counter incrementing.
It is based on iterating over the video while there are frames available.
Tiltshift bondage code#
The previous chunk of code is the video processing itself. When the user is done, he/she must press any button, causing the UI to disapear and the video processing to take place. The idea of this chunk of code is to get the first video frame and display it on the user interface so the user can choose the processing parameters that I defined above.
Tiltshift bondage how to#
The code also shows on terminal the amount of frames because at the point I wrote such line I was not sure about how to discard the frames to make the stopmotion effect, and I wanted to see how many frames there exist (confused, I know).įrom this point to line 144 we see the same tiltshift processing we have in the tiltshift file. A cv::VideoCapture object reads such string.ĭuring debugging I was doubtful if the code was reading the right argument, then I displayed the path using std::cout. Since the program will be executed via terminal, the image path must be provided via that means. get ( cv :: CAP_PROP_FRAME_COUNT ) << " frames no video \n " Std :: cout << argv cv :: VideoCapture cap ( argv ) std :: cout << " \n existem " << cap. Again, if you want to now more about how it works, please read my post about it. The first ninety lines are roughly tiltshift stuff: slider functions and image processing. Through the explanation I will detail only the aspects that do not relate to tiltshift itself, given that I have explained tiltshift in another post. I even watched Agostinho’s class about the topic to understand more about it, but at the end I couldn’t arrange the compiler instructions to make it work, so let’s go with only one file. I actually wanted the system to work using Modular Programming. After the user chooses the parameters, the video is processed, displayed and saved.When the program starts running, it needs to display a screen so the user can choose the parameters of tiltshifting (area of focus, basically).I designed the program to work following the steps: To get rid of some frames in the video to create the effect of the scene not being really continuous. We know how to make a tiltshift image already, right? To make a stopmotion video, we will need just What about to make entire stopmotion like videos? Such idea is the other task assigned by my professor Agostinho on his blog on the topic “Spacial Filtering”. Now we know how to make tiltshift images. It was something even more interesting: stopmotion like video! It was not only a collection of tiltshift images. In a previous post I introduced the concept of tiltshift using an example video at the top of the post. More References To Make this Post Possible.
