Live video to sketch using deep learning is a process of converting a live video stream into a sketch or a line drawing in real-time using machine learning algorithms. This involves training a deep learning model to recognize and extract edges and contours from the video frames, and then applying a sketching algorithm to generate the final output. The goal of this process is to provide a new and interesting way to view live video content, as well as to enable new applications such as real-time sketching and artistic rendering of video content. The process typically involves several steps including data collection, preprocessing, training the model, and finally applying the model to the live video stream.
