It is difficult to segmentation and recognition of FLIR image due to blurry edge, we introduced a recognition algorithm base on template matching. The reference image is created depending on the satellite dates and then created the template image, characteristic scale of target areas can be chosen as prior knowledge according to normalize LoG response. Using these scales, a number of blob-like candidate regions can be found with the same size with template image. Then the final result is obtained between candidate regions and the template image using Hasudorff measure. The experimental result shows that method have highly precision and quickly performance. It is useful to recognition of complex ground fixed garget.
