Evidence Base Gaps Exposed in First Part

In the realm of media and entertainment, the importance of representation cannot be overstated. However, current evidence on diversity in on-screen representation often focuses on presence — whether someone appears on screen — and overlooks other crucial aspects such as prominence. This is where computer vision comes into play, offering a promising solution to address these gaps.

Computer vision has the potential to expand the evaluation of on-screen representation from mere presence to prominence — screen time, centering, and portrayal. By leveraging advanced detection and localization, attribute classification, vision-language integration, domain-aware data strategies, and geometric image analysis, researchers can develop a comprehensive, multi-dimensional evaluation framework.

Advanced object detection and visual grounding models locate and segment on-screen subjects precisely, enabling measurement of their size, position, and duration in video frames or images. This quantifies prominence by factors such as screen space occupied, centrality, and attention-grabbing cues. For example, vision-language models fine-tuned on UI datasets improve visual grounding accuracy, allowing detailed analysis of UI elements and on-screen personas.

Computer vision techniques also extract nuanced attributes related to portrayal, such as facial expressions (e.g., emotions), demographic traits (gender, age, race), and identity features while ensuring privacy-preserving methods. Models trained for emotion classification and demographic prediction can provide rich metadata about on-screen representation beyond presence.

Moreover, vision-language models that integrate visual perception with natural language understanding enable semantic interpretation of portrayal — captioning scenes, describing roles or actions associated with characters, and grounding these descriptions spatially and temporally. Efficient models like FastVLM process high-resolution images with low latency, enabling real-time analysis of fine-grained details necessary for assessing prominence and portrayal.

Addressing data gaps and limitations is another key aspect of this approach. Combining diverse datasets with synthetic augmentation and domain-specific training improves model robustness across content types (e.g., desktop, mobile, automotive UIs). Visualization tools help identify domain performance variations and failure modes, encouraging more targeted data collection and model refinement. Privacy-preserving approaches in identity and attribute extraction help ethically fill gaps without compromising sensitive information.

The use of computer vision can speed up data compilation, provide new insights, and widen the evidence base from presence to prominence. Initiatives like the Creative Diversity Network's Project Diamond and Ofcom's annual diversity in television broadcasting reports are two major UK initiatives collecting diversity data. Embracing and building upon new evidence methods, like computer vision, can help address gaps in the evidence base for representation.

It's essential to note that while the wider social norms around applying facial technologies responsibly and ethically are still developing, the potential benefits of computer vision in expanding the evaluation of on-screen representation are undeniable. As research in this area progresses, it is crucial to ensure that these advancements are applied responsibly and ethically, prioritizing fairness and inclusivity in the media and entertainment industry.
