Abstract: Opto-electronic hybrid converter can be combined to achieve the target of real-time detection, identification and automatic location, but the low-contrast targets related peak intensity is very weak, or even no correlation peak, affecting the target recognition rate. Filtering to enhance the use of high-boost filtering and image segmentation of the power spectrum for the enhanced process, it can effectively improve the power spectrum of contrast, the maximum spectral images to retain the details of information to enhance co-related systems photoelectric target recognition rate.

Key words: joint transform correlator, high-boost filtering, power spectrum, image enhancement, image segmentation
