Abstract

Real-Time Video Extraction is a Python project that uses machine learning to extract videos in real-time. The application features data preprocessing, model training, and a CLI interface, demonstrating best practices in computer vision and ML.

Prerequisites

• Python 3.8 or above
• A code editor or IDE
• Basic understanding of ML and computer vision
• Required libraries: pandaspandas, scikit-learnscikit-learn, matplotlibmatplotlib, opencv-pythonopencv-python

Before you Start

Install Python and the required libraries:

pip install pandas scikit-learn matplotlib opencv-python

pip install pandas scikit-learn matplotlib opencv-python

Getting Started

Create a Project

1. Create a folder named real-time-video-extractionreal-time-video-extraction.
2. Open the folder in your code editor or IDE.
3. Create a file named real_time_video_extraction.pyreal_time_video_extraction.py.
4. Copy the code below into your file.

Write the Code

import numpy as np
 
class RealTimeVideoExtraction:
    def __init__(self):
        pass
 
    def extract_features(self, frames):
        # Dummy feature extraction for demo
        print("Extracting features from video frames...")
        return [np.mean(frame) for frame in frames]
 
    def demo(self):
        frames = [np.random.rand(32, 32) for _ in range(5)]
        features = self.extract_features(frames)
        print(f"Extracted features: {features}")
 
if __name__ == "__main__":
    print("Real-Time Video Extraction Demo")
    extractor = RealTimeVideoExtraction()
    extractor.demo()
 

import numpy as np
 
class RealTimeVideoExtraction:
    def __init__(self):
        pass
 
    def extract_features(self, frames):
        # Dummy feature extraction for demo
        print("Extracting features from video frames...")
        return [np.mean(frame) for frame in frames]
 
    def demo(self):
        frames = [np.random.rand(32, 32) for _ in range(5)]
        features = self.extract_features(frames)
        print(f"Extracted features: {features}")
 
if __name__ == "__main__":
    print("Real-Time Video Extraction Demo")
    extractor = RealTimeVideoExtraction()
    extractor.demo()

from sklearn.ensemble import RandomForestRegressor
import matplotlib.pyplot as plt

2. Data Preprocessing and Model Training Functions

def preprocess_data(df):
    return df.dropna()
 
def train_model(X, y):
    model = RandomForestRegressor()
    model.fit(X, y)
    return model

def preprocess_data(df):
    return df.dropna()
 
def train_model(X, y):
    model = RandomForestRegressor()
    model.fit(X, y)
    return model

3. CLI Interface and Error Handling

def main():
    print("Real-Time Video Extraction")
    # df = pd.read_csv('videos.csv')
    # X, y = df.drop('pixels', axis=1), df['pixels']
    # model = train_model(X, y)
    print("[Demo] Video extraction logic here.")
 
if __name__ == "__main__":
    main()

def main():
    print("Real-Time Video Extraction")
    # df = pd.read_csv('videos.csv')
    # X, y = df.drop('pixels', axis=1), df['pixels']
    # model = train_model(X, y)
    print("[Demo] Video extraction logic here.")
 
if __name__ == "__main__":
    main()
