# Model Card for samanthajmichael/siamese_model.h5
|
| 28 |
+
|
| 29 |
+
This Siamese neural network model detects match cuts in video sequences by analyzing the visual similarity between frame pairs using optical flow features.
|
| 30 |
+
|
| 31 |
+
## Model Details
|
| 32 |
+
|
| 33 |
+
### Model Description
|
| 34 |
+
|
| 35 |
+
The model uses a Siamese architecture to compare pairs of video frames and determine if they constitute a match cut - a film editing technique where visually similar frames are used to create a seamless transition between scenes. The model processes optical flow representations of video frames to focus on motion patterns rather than raw pixel values.
|
| 36 |

+
- **License:** Not specified
|
| 41 |
+
- **Finetuned from model:** EfficientNetB0 (used for initial feature extraction)
|
| 42 |
+
|
| 43 |
+
### Model Sources
|
| 44 |

+
## Uses
|
| 48 |
+
|
| 49 |
+
### Direct Use
|
| 50 |
+
|
| 51 |
+
The model can be used to:
|
| 52 |
+
1. Detect match cuts in video sequences
|
| 53 |
+
2. Find visually similar sections within videos
|
| 54 |
+
3. Analyze motion patterns between frame pairs
|
| 55 |
+
4. Support video editing and content analysis tasks
|
| 56 |
+
|
| 57 |
+
### Downstream Use
|
| 58 |
+
|
| 59 |
+
The model can be integrated into:
|
| 60 |
+
- Video editing software for automated transition detection
|
| 61 |
+
- Content analysis tools for finding visual patterns
|
| 62 |
+
- YouTube video analysis applications (as demonstrated in the provided Streamlit app)
|
| 63 |
+
- Film studies tools for analyzing editing techniques
|
| 64 |
+
|
| 65 |
+
### Out-of-Scope Use
|
| 66 |
+
|
| 67 |
+
This model is not designed for:
|
| 68 |
+
- Real-time video processing
|
| 69 |
+
- General object detection or recognition
|
| 70 |
+
- Scene classification without motion analysis
|
| 71 |
+
- Processing single frames in isolation
|
| 72 |
+
|
| 73 |
+
## Bias, Risks, and Limitations
|
| 74 |
+
|
| 75 |
+
- The model's performance depends on the quality of optical flow extraction
|
| 76 |
+
- May be sensitive to video resolution and frame rate
|
| 77 |
+
- Performance may vary based on video content type and editing style
|
| 78 |
+
- Not optimized for real-time processing of high-resolution videos
|
| 79 |
+
|
| 80 |
+
### Recommendations
|
| 81 |
+
|
| 82 |
+
Users should:
|
| 83 |
+
- Ensure input frames are properly preprocessed to 224x224 resolution
|
| 84 |
+
- Use high-quality video sources for best results
|
| 85 |
+
- Consider the model's confidence scores when making final decisions
|
| 86 |
+
- Validate results in the context of their specific use case

+
from huggingface_hub import from_pretrained_keras
|
| 92 |
+
import tensorflow as tf
|
| 93 |
+
|
| 94 |

|
| 95 |
+
model = from_pretrained_keras("samanthajmichael/siamese_model.h5")
|
| 96 |
+
|
| 97 |
+
# Preprocess your frame pairs (ensure 224x224 resolution)
|
| 98 |
+
# frames should be normalized to [0,1]
|
| 99 |
+
frame1 = preprocess_frame(frame1) # Shape: (224, 224, 3)
|
| 100 |
+
frame2 = preprocess_frame(frame2) # Shape: (224, 224, 3)
|
| 101 |
+
|
| 102 |
