Return **only** the complete Python function code.

user: Complete this Python function:

**DESCRIPTION:** Implements recursive contour detection algorithm for complex shapes with multiple nested holes using Euler number calculation and iterative binary hole filling. Handles topology preservation for accurate shape representation in QCL-MIR imaging.

**KEY TERMS:** {
  "euler_number": "topological invariant for hole detection",
  "binary_fill_holes": "hole filling operation",
  "contours_outer_shape": "outer boundaries of regions",
  "contours_holes": "hole boundaries within regions"
}

**CONTEXT CODE:** """
This functions helps to recognize counts with holes.
