# Intorduction
We create the defect detection solutions on EXMU-X261. When camera catch the image, the image will input to EXMU-X261. The EXMU-X261 will preprocess the image. After all, the DPU will inference image and output result with bounding box. The result will shows on screen.


|Solution| Model | Input Size | AVG. FPS on X261 |
|:------:| :-------------: |:----: |:---:|
| Object detection | YOLOv4-tiny | 320x320 | ~35 FPS |

`In the following section we have presented 3 case studies for you with object detection solution.`

# Pre-build image
We provide pre-built images that you can use to follow the [Getting Started](https://hackmd.io/pOWB6eGzTp6x0TFhtse--g) guide to prepare the SD card. By switching X261 to boot from the SD card, you can experience our solution.
