Crafting Image Prompts with Scene-Specific Structures

The Breniapp/brenia project is focused on image generation. A new feature has been implemented to structure image prompts based on the scene type, allowing for more tailored and realistic outputs.

The Problem: Generic Prompts

Previously, image prompts were often generic, leading to inconsistent and sometimes unrealistic results. A single prompt structure couldn't effectively capture the nuances of different scene types, such as portraits, landscapes, or product shots.

The Solution: Scene-Specific Prompt Structures

To address this, the system now uses a SceneType enum and an induction wizard to classify images into three categories: people, scene, and product. This classification allows the application of specialized prompt structures tailored to each category.

Here's how the buildImagePrompt() function adapts prompts:

enum SceneType {
    case People;
    case Scene;
    case Product;
    case Generic;
}

function buildImagePrompt(SceneType $sceneType, string $basePrompt): string {
    switch ($sceneType) {
        case SceneType::People:
            return "hyperrealistic Latin diversity with skin textures, culture-aware. " . $basePrompt;
        case SceneType::Scene:
            return "UHD environment photography with ambient detail. " . $basePrompt;
        case SceneType::Product:
            return "professional product photography with material textures. " . $basePrompt;
        default:
            return $basePrompt; // Generic prompt
    }
}

This PHP code demonstrates how the buildImagePrompt function uses a SceneType enum to apply specialized prompt structures. Depending on the identified scene type (People, Scene, or Product), a specific prefix is added to the base prompt, enhancing the image generation process.

Benefits of Structured Prompts

• Increased Realism: Scene-specific prompts lead to more realistic and contextually appropriate images.
• Improved Diversity: Tailoring prompts for people scenes allows for better representation of diversity.
• Enhanced Detail: Specialized prompts can emphasize specific details, such as skin textures or material textures, depending on the scene type.

Actionable Takeaway

Consider using structured prompts in your image generation projects. By categorizing images based on scene type and applying specialized prompts, you can achieve more realistic, diverse, and detailed results.
