Introduction
In the vast Japanese adult film industry, numbers have always been the most important indexing method. When viewers want to find a particular film, they often rely on number searches. However, the problem lies in the complexity of the numbering system and the large number of actors, leading viewers to often remember the scene but forget the number.
Today, the introduction of artificial intelligence makes 'image-based number search', 'actress recognition', and 'scene restoration' possible. This article will unveil the AI black technology behind number recognition and demonstrate how this technology changes the search experience through case studies.
Core Principles of Number Recognition
Image Feature Extraction
- Using Convolutional Neural Networks (CNN) to extract key features from screenshots;
- These feature vectors are compared with the video fingerprints in the film database;
- Even with blurry screenshots, key information can be restored.
👉 For example: Uploading a blurry classroom scene screenshot of Yua Mikami, the AI can still accurately match the corresponding film number.
Database Comparison
- The database pre-stores millions of key frames from films;
- The system quickly matches results through similarity calculations;
- Outputs: number, actor, timestamp.
Image-Based Actress Search: AI's Facial Recognition Technology
Facial Vector Comparison
The AI extracts the facial features of the actress and compares them with the facial templates of actresses in the database.
- Ai Kawai: recognized through her eyes and facial contours;
- Tsukasa Aoi: identified by facial shape and hairstyle features;
- Popular Saito: nearly instant match due to her highly recognizable facial features.
Case Demonstration
- Uploading a pool photo of Ai Kawai;
- The AI immediately outputs the film number and lists her other notable works;
- The system can also recommend similar pool-themed films featuring Moe Kamiji or Momo Sakura.
Scene Restoration: How AI Understands the Environment
Scene Recognition Technology
The AI not only recognizes faces but can also identify background scenes:
- Pool: water surface texture + blue background;
- Office: characteristics of desks, chairs, whiteboards, computers, etc.;
- Massage Room: bed, lighting, decorations;
- Classroom: blackboard, desks, school uniform elements.
Practical Applications
- Uploading a scene screenshot from Tsukasa Aoi's office → The system identifies it as an office scene → Outputs the corresponding film number;
- Uploading a pool scene of Saito Popular → Pinpointing to the 14th minute of the film → Simultaneously recommending pool-related scenes of the same series.
Challenges in Number Recognition
- Large Number of Actresses: There are thousands of adult actresses in Japan, making database management extremely difficult.
- Similarity Issues: Some actresses (like Momo Sakura and Ichika Matsumoto) have similar appearances, requiring more precise algorithms.
- Poor Screenshot Quality: The recognition accuracy decreases when dealing with older films or blurry user screenshots.
- Data Updates: New films are constantly being released, requiring the database to be updated in real-time.
Platform Comparison: whos.tv vs. Mainstream Sites
- pornhub.com: primarily focused on video aggregation, lacking AI search functionality;
- javdb.com: provides a number database, but can only rely on text input;
- whos.tv: achieves a complete loop through image-based number search, actress recognition, and scene restoration, truly addressing the pain point of "finding films by image."
👉 This is the differentiated advantage of whos.tv.
Future Prospects
Multimodal Search
- Users can upload screenshots + input text (such as “Yua Mikami pool”), improving accuracy.
Personalized Recommendations
- The system recommends similar actors and plots based on search history.
- For example: searching Ai Kawai pool recommends Moe Kamiji pool.
Globalization and Compliance
- AI search will support multilingual subtitle matching in the future;
- whos.tv has the opportunity to become a global search platform that understands Japanese adult films better than pornhub.com.
Conclusion
The black technology behind number recognition has transformed AV searches from "input text" to "image recognition". Through image feature extraction, actress recognition, facial recognition, and scene restoration, AI helps users easily find numbers and films.
From The classroom scene of Yua Mikami to The pool clip of Ai Kawai, and even the representative works of Popular Saito and Tsukasa Aoi, AI is reconstructing the user’s film-finding experience. In the future, with the development of multimodal search and personalized recommendations, platforms like whos.tv will redefine the way audiences connect with Japanese adult films.
