Motion-Text Classifier Dataset

A binary classification dataset for distinguishing between pure motion and text-revealed-through-motion in speckle noise videos.

Dataset Description

This dataset contains 1000 videos (5 seconds each) designed to test motion-based perception:

• Motion-only (500 videos): Pure background noise scrolling horizontally
• Text videos (500 videos): Single words revealed through opposing foreground/background motion

All videos use identical noise parameters to ensure the only distinguishing feature is the presence of foreground content.

Usage

from datasets import load_dataset

# Load dataset
dataset = load_dataset("mukul54/motion-text-classifier")

# Access samples
train_sample = dataset['train'][0]
print(train_sample['label'])  # 'motion_only' or 'text_fg_bg'
print(train_sample['text'])   # word shown (None for motion_only)

Video Parameters

All videos share identical generation parameters:

Parameter	Value
Resolution	960×540
FPS	60
Duration	5.0 seconds
Noise Density	0.5
Speckle Size	1
Speed	2
Direction	Horizontal

Labels

• motion_only: Background noise only (no foreground object)
• text_fg_bg: Text revealed through opposite motion of foreground/background using the same noise pattern

Key Features

• Pure motion detection: Text is invisible in static frames
• Controlled experiment: All parameters identical except foreground content
• Temporal encoding: Information only available through motion analysis

Use Cases

• Testing motion perception in vision models
• Temporal feature extraction benchmarks
• Zero-shot video understanding
• Motion-based object detection
