OpenCVSharp Rotation Angle Detection

Job ID: 39700906

Budget: $20 – $21 USD

I need a simple code block to determine the rotation angle of a simple object after matching it to a table image using OpenCVSharp in C#. The images will be in PNG format.

Requirements:
- Use OpenCVSharp for image processing
- Match a simple object image to a table image
- Calculate rotation angle (counterclockwise is positive)
- Use C#
- Provide basic comments in the code

Ideal Skills:
- Proficiency in C#
- Experience with OpenCV and OpenCVSharp
- Image processing and feature matching expertise
