Hello EVERYONE,lets do some magic using computer vision. I hope you all know about ‘invisible cloak’, this will make you invisible. We will see how we can do the same magic trick with the help of computer vision. I will code with python and use the opencv and numpy library.
Our purpose is to become Invisible using a cloak with the help of various Python libraries.
- Install the latest python 3.5 and above and once you finish installing it .
- Add opencv library.
- Add Numpy library.
We wll learn how to create our own ‘Invisibility Cloak’ using simple computer vision techniques in OpenCV. Here we have written this code in Python because it provides exhaustive and sufficient library to build this program.
Here, we will create this magical experience using an image processing technique called Color detection and segmentation. In order to run this code, you need an mp4 video named “video.mp4“. You must have a cloth of same color and no other color should be visible into that cloth. We are taking the red cloth. If you are taking some other cloth, the code will remain the same but with minute changes.
firstly the program when you run it it will capture the background image and then. When you put a red colored colored cloth in front of camera the program will detect the colored cloak using color detection and segmentation algorithm . And the program will generate a mask to determine the region in the frame corresponding to the detected color(red in this case). Program will refine this mask and then use it for segmenting out the cloth from the frame. Program will replace the pixels value of the detected red color region with corresponding pixel values of the static background.
- Capture and store the background frame
- Detect the defined color using color detection and segmentation algorithm.
- Segment out the defined colored part by generating a mask.
- Generate the final augmented output to create a magical effect.
