Champion selection in League of Legends is crucial for a player's success. While existing methods rely on tier lists, win rates, and general meta, they fail to personalize recommendations based on an individual’s actual gameplay behavior.
To address this, we propose an AI-based system that processes live gameplay recordings and extracts player tendencies to suggest champions that complement their strengths.

Our method leverages a pre-trained convolutional neural network (CNN) model to predict cooldown states from gameplay videos. The key steps of the method are as follows:
We preprocess the input gameplay video to extract relevant cooldown regions. Specific areas corresponding to ability cooldown icons are cropped from each frame based on predefined coordinates. This approach allows the system to focus on the cooldown regions of interest, ignoring irrelevant parts of the frame.
We defined the crop areas for each ability's cooldown region, allowing the model to analyze each ability separately. The cropping coordinates (left, upper, right, lower) were consistent across all video frames and represent the regions where cooldown icons appear on the gameplay screen. The defined cropping areas are as follows:
Ability Q: (480, 620, 525, 680)
This region contains the cooldown icon for the Q ability.
Ability W: (530, 620, 570, 680)
This region contains the cooldown icon for the W ability.
Ability E: (575, 620, 612, 680)
This region contains the cooldown icon for the E ability.
Ability R: (615, 620, 660, 680)
This region contains the cooldown icon for the R ability.
By applying this cropping to each frame, we ensure that the deep learning model only processes the relevant cooldown regions, improving both efficiency and accuracy.
We use a deep learning model based on the CNN architecture. The model takes the cropped regions as input and predicts the probability of an ability being on cooldown. If the predicted probability exceeds a threshold (0.5), the system classifies the ability as "Cooldown Detected." Otherwise, it is classified as "No Cooldown." The model can process multiple cooldown regions simultaneously, enabling real-time tracking.

In this method, we trained a custom model from scratch without relying on YOLOv8. The steps include:
Data Preprocessing and Feature Extraction: We used gameplay recordings to extract key metrics such as KDA (Kills/Deaths/Assists), champion abilities, item builds, and other in-game elements.
Model Design: A deep learning model was built using CNN-based architectures designed to handle gameplay data, and trained directly on the dataset, where both images and associated labels were used to predict in-game metrics.
Evaluation and Training: The model was trained on the annotated dataset using regression techniques to predict various gameplay attributes. Evaluation was carried out with accuracy metrics tailored to the gameplay objectives.
In this approach, we used YOLOv8 for object detection to extract gameplay features, focusing on the following steps:
Real-Time Gameplay Data Extraction: We analyzed game recordings frame-by-frame to extract UI elements like champion abilities, KDA, and item builds using YOLOv8-based object detection.
Feature Processing and Analysis: The extracted features were processed using machine learning techniques for clustering and playstyle analysis.
Champion Recommendation: Deep learning models and collaborative filtering were used to suggest champions based on the player’s playstyle.
Our approach is divided into the following key steps:
Live game recordings are analyzed frame-by-frame.
YOLOv8-based object detection identifies UI elements such as:
Champion abilities usage
KDA (Kills/Deaths/Assists)
Item builds
Objective control (Dragon, Baron, Turrets)
Vision score (Wards placed/destroyed)
Gold income and CS (Creep Score)
Extracted gameplay features are processed using unsupervised learning techniques:
K-Means, DBSCAN, or t-SNE to classify players into playstyle categories (e.g., Aggressive, Defensive, Objective-focused, etc.).
Comparison against a database of professional and high-rank players for additional insights.
A recommendation system built with:
Collaborative filtering (suggesting champions based on similar players).
Deep learning models (Transformer-based ranking, Siamese Networks) to suggest champions aligning with the player's preferred strategy.
Dataset Annotation Process (Using RoboFlow)

Ability Q
Ability W
Ability E
Ability R
In-Game Metrics:
HP (Health Points)
Mana

✅ No Need for Detailed Annotation: Unlike many traditional computer vision projects, the need for extensive manual labeling was eliminated by focusing solely on cropped images containing the spell icons. This approach simplified the dataset generation process, as each crop corresponds directly to an ability’s cooldown state, removing the complexity of labeling entire in-game frames.
✅ Improved Generalization: Initial models struggled with generalization, misclassifying objects in the dataset due to poor feature extraction. By refining the cropping process and improving the CNN architecture, the model now reliably detects cooldown states across different gameplay scenarios, as reflected in a much-improved confusion matrix.
✅ Fixed Training Loss Issues: Earlier issues with high training loss were addressed by ensuring consistency in the cropped input images and making necessary adjustments to the model’s architecture. This led to a significant reduction in training loss, with the model now showing steady learning progress across epochs.
❌ Complex UI Element Handling: While other dynamic UI elements (HP bar, CS, item purchases) were not within the scope of this project, we streamlined the detection system to focus on ability cooldowns, which simplified the overall approach.
❌ Batch Frame Annotation: Due to the efficiency of our cropping-based approach, there was no need for batch frame annotation. The model processes specific regions of interest related to ability cooldowns, further optimizing performance and reducing overhead.

✅ High Accuracy in Cooldown Detection: By leveraging a color-based CNN and focusing on cropped regions containing only the ability icons, the model achieved high detection accuracy for cooldown states across multiple abilities.
✅ Optimized for Real-Time Scenarios: The model now performs accurately and efficiently in real-time gameplay scenarios, making it suitable for live usage. It consistently provides correct cooldown state predictions for all tracked abilities (Q, W, E, R).
❌ UI Element Detection Out of Scope: While the model excels at cooldown detection, other dynamic UI elements (HP bar, CS, item purchases) were not addressed in this iteration, focusing solely on ability tracking.
By integrating real-time gameplay data analysis, this system provides a personalized, AI-driven approach to champion selection.
This project bridges AI, computer vision, and esports analytics to revolutionize League of Legends champion selection. However, the current model performance is poor, and improvements are necessary before real-world deployment.
Focusing on implementing detection for hp, mana, cs, ping and etc.
