Interactive Generation of Image Variations for Copy-Paste Data Augmentation

Introduction

Introduction

Data augmentation is a crucial technique in machine learning, particularly in the realm of image processing, as it allows the synthesis of numerous variations from a limited set of training data. Traditionally, advanced data augmentation methods required coding skills, presenting a barrier for many practitioners. In this work, we present a graphical editor designed to generate image variations effortlessly, without the need for programming.

Graphical Editor Features

The proposed tool takes the form of a standard image editor, equipped with intuitive functionalities. A notable feature of this system is that each property comes with adjustable ranges, enabling the user to synthesize a multitude of image variations within these predefined limits.

User Interaction

The process begins when the user imports an image object into the editor. The user then has the opportunity to modify various parameters:

• Position and Orientation: The user adjusts the location and angle of the image.
• Ranged Adjustments: By setting ranges for the x-coordinates, the user can influence the variations effectively. After inputting the desired ranges, pressing the preview button allows the user to visualize varying outcomes.
• Scale and Opacity: Users can also specify ranges for scale and opacity using text fields.

Once satisfied with the adjustments made, the user initiates the synthesis process, and the system organizes the generated image variations for storage.

Spray Tool Functionality

An exciting feature of this tool is the spray tool, which enables users to synthesize multiple instances of a single object. The user defines:

• Target Region: Where the objects will be placed.
• Source Object: The object to replicate.
• Number of Instances: Users can also specify the range for the total instances to be generated.

Practical Applications

The capabilities of the graphical editor extend to various applications:

• Tomato Detection: Tomatoes and leaves are randomly placed using the spray tool to create diverse training scenarios.
• Object Counting: Multiple copies of cotton pearls are generated on a plate to enhance counting algorithms.
• Object Tracking: An invisible marker is placed at the fingertip for tracking applications.
• Stain Detection: The tool assists in fabricating hand-painted stains on carpets without relying on natural stain images.
• Stock Monitoring: Juice boxes can be realistically positioned on shelves for inventory analysis.
• Biological Studies: The spray tool generates numerous copies of cells, aiding in biological examinations.

Conclusion

This graphical editor represents a significant advancement in data augmentation, allowing users without coding knowledge to generate diverse image variations efficiently. Its intuitive interface, combined with powerful features like adjustable ranges and the spray tool, opens up new avenues for enhancing machine learning applications in various fields.
