Episode 2: Multimedia I/O
Learn to manipulate images from various sources: JPG and PNG files, and USB webcams. Run standard filters such as Sobel, then learn to display and output back to file. Implement a rudimentary video playback mechanism for processing and saving sequential frames.
The instructor introduce a few concepts in different steps.
Step 1 : Showing lena’s picture
Step 2 - 3 : Creating a sobel lena and saving it to disk
Step 4 - 5 : Loading a video from disk, apply sobel to its frames and saving the video
The video I used was the SDCND Vehicle Detection project. The video is car.mp4 and the sobel version is car_sobel.avi or you can see it here.
