# ST Yolo X quantized |
|
|
|
|
|
## **Use case** : `Object detection` |
|
|
|
|
|
# Model description |
|
|
|
|
|
|
|
|
ST Yolo X is a real-time object detection model targeted for real-time processing implemented in Tensorflow. |
|
|
This is an optimized ST version of the well known yolo x, quantized in int8 format using tensorflow lite converter. |
