Getting Started

Create a Project

1. Create a folder named real-time-video-classificationreal-time-video-classification.
2. Open the folder in your code editor or IDE.
3. Create a file named real_time_video_classification.pyreal_time_video_classification.py.
4. Copy the code below into your file.

Write the Code

import numpy as np
import matplotlib.pyplot as plt
 
class RealTimeVideoClassification:
    def __init__(self):
        pass
 
    def classify_video(self, frames):
        # Dummy classification for demo
        print("Classifying video frames...")
        return np.random.randint(0, 2, len(frames))
 
    def demo(self):
        frames = [np.random.rand(64, 64) for _ in range(10)]
        labels = self.classify_video(frames)
        print(f"Frame labels: {labels}")
        plt.plot(labels, marker='o')
        plt.title('Video Frame Classification')
        plt.xlabel('Frame')
        plt.ylabel('Label')
        plt.show()
 
if __name__ == "__main__":
    print("Real-Time Video Classification Demo")
    classifier = RealTimeVideoClassification()
    classifier.demo()
 

import numpy as np
import matplotlib.pyplot as plt
 
class RealTimeVideoClassification:
    def __init__(self):
        pass
 
    def classify_video(self, frames):
        # Dummy classification for demo
        print("Classifying video frames...")
        return np.random.randint(0, 2, len(frames))
 
    def demo(self):
        frames = [np.random.rand(64, 64) for _ in range(10)]
        labels = self.classify_video(frames)
        print(f"Frame labels: {labels}")
        plt.plot(labels, marker='o')
        plt.title('Video Frame Classification')
        plt.xlabel('Frame')
        plt.ylabel('Label')
        plt.show()
 
if __name__ == "__main__":
    print("Real-Time Video Classification Demo")
    classifier = RealTimeVideoClassification()
    classifier.demo()

from sklearn.ensemble import RandomForestClassifier
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 = RandomForestClassifier()
    model.fit(X, y)
    return model

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

3. CLI Interface and Error Handling

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

def main():
    print("Real-Time Video Classification")
    # df = pd.read_csv('videos.csv')
