+## ✨ Features
+- **Multiple Detection Methods**:
+  - **YOLOv8**: Fast and accurate ONNX-based detection
+  - **MCCardDetector**: OpenCV's mcc module for robust color checker detection
+- **Segmentation Support**: Detect color checker cards using quadrilateral segmentation regions
+- **Multiple Correction Models**: Choose from `polynomial`, `least_squares`, `affine_reg`, or `linear_reg`
+- **GPU Support**: Optional GPU acceleration for faster processing
+- **Comprehensive Analysis**: Built-in analyzer for comparing different correction methods and detection approaches

 ## 🤸 TODO
 - [ ] Add Loggers
-- [x] Add detection MCC:CCheckerDetector from opencv
-- [ ] Add Segmentation Color Checker using YOLOv11 ONNX
+- [x] Add detection MCCardDetector from OpenCV's mcc module
+- [x] Add Segmentation support for Color Checker detection
 - [ ] Improve validation preprocessing (e.g., auto-match-orientation CC)
 - [ ] Add more analysis and evaluation metrics (Still thinking...)
