W ith the application o fData Matrix in people’s daily life and industrial product

the detection of Data Matrix has become very useful. The existing detection algorithm is only suitable for printed paper; it can notbe used to detect Data Matrix which is punched on other material surfaces. This paperpresents a machine learning based on the method which can detect the Data Matrix on various surfaces. We extend the Ada Boost algorithm to Adaptive-Spatial Boost which can adaptively combine the texture information and spatial connection. The Data Matrix detector trained by this algorithm has achieved 100% detection rate on the test samples in our experiment.
