Abstract: The target detection of digital image is one of the main content in computer vision research, which is used widely. This paper presents an algorithm for the foggy small targets detection. Firstly, all the pixel values are looked as a set of elements with the corresponding address, and the small target is selected according to the needs, so the pixels are divided into two sets, one is object set and the other is complementary set; then the addresses of the target pixels are located; the next step is calculating the thresholds of target set and its complementary set. Finally, the binarization operation is applied to the small target set and its complement set by the threshold. The test results show that this algorithm for small target detection is very effective.
