Abstract :
In this paper we propose a new two dimensional (2D) barcode detection algorithm. This algorithm can generally be proposed for high density codes with very small projected image. This algorithm is a simplified expression of the sum product algorithm (SPA). We apply it in a joint detection and decoding structure and then we will compare it with known 2D barcode decoding technique.
