Iterative methods represent another class of techniques for solving linear algebraic equation systems, particularly effective for large sparse linear systems. These methods operate by designing specific iterative schemes that generate sequences of approximate solutions, which converge toward the exact solution when properly formulated. The implementation typically involves matrix-vector multiplications and residual calculations, requiring only O(n) storage for sparse systems. Key advantages include constant coefficient matrices throughout iterations, algorithmic simplicity, straightforward programming implementation, and reduced memory requirements compared to direct methods.

Background extraction using iterative method (Surendra algorithm); utilizes frame differencing technique where current frame is subtracted from previous frame to identify moving regions. By eliminating these dynamic areas, static background is obtained. The iterative approach processes multiple frames to achieve more accurate background estimation.
