Home » Case Study » Facial Attribute Dataset – CelebA

Project Overview:

Objective

The primary goal is to curate a dataset that enhances the capabilities of facial recognition systems by encompassing diverse facial attributes present in real-world scenarios. To achieve this, we will actively identify and include a wide range of facial attributes, such as different skin tones, ages, and facial expressions. Additionally, we will ensure the dataset features a variety of lighting conditions and angles to better simulate real-world scenarios.

Scope

The Facial Attribute Dataset – CelebA encompasses an extensive array of facial characteristics, including gender, age, facial expressions, presence of accessories, and ethnicity, among others. Moreover, this dataset captures the complexity of real-world scenarios by incorporating diverse lighting conditions, variations in facial orientations, and instances of occlusions. Consequently, it simulates a broad spectrum of real-life situations, providing a robust and comprehensive resource for training and testing facial attribute recognition algorithms.

Sources

Real-world Image Collection: We source data from various real-life scenarios, thereby capturing individuals from different demographics and environments.
First and foremost, we gather images from diverse locations, ensuring a wide representation of different backgrounds. Additionally, we actively seek out individuals from various age groups, ethnicities, and socioeconomic statuses.
Synthetic image generation involves creating artificial images to augment datasets, ensuring diversity and comprehensiveness. By using synthetic images, we can effectively enhance the variability and scope of our datasets.
Firstly, synthetic images are generated to augment the dataset. This process, in turn, ensures diversity and comprehensiveness. Furthermore, these artificially created images play a crucial role in expanding the range of scenarios our dataset can cover.

Data Collection Metrics

Total Data Collected: 100,000 images with accompanying attribute labels.
Data Annotated for ML Training: 120,000 images annotated with detailed attribute labels suitable for machine learning models.

Annotation Process

Stages

Attribute Classification: We meticulously label each facial attribute, including gender, age, and expression, to facilitate attribute recognition tasks. Consequently, this detailed labeling ensures that we accurately recognize these attributes. Furthermore, employing active voice emphasizes the importance of each labeled attribute in improving the efficiency of recognition tasks.
Region of Interest Annotation: We identify and annotate specific facial regions containing attributes of interest to ensure precise attribute detection. First, we pinpoint specific facial regions harboring these attributes. Then, we meticulously annotate these regions. This active process enables us to guarantee precise attribute detection.
Occlusion Handling: Annotations comprehensively account for occlusions such as facial hair, glasses, and hats, thereby ensuring robustness in attribute recognition. Additionally, they meticulously identify these elements, which allows for a more precise analysis. Consequently, this attention to detail enhances the overall accuracy and reliability of the attribute recognition process.
